Rimfire and Northgate Commence Drilling at Boulevard, Yukon

Vancouver, BC -- September 23, 2008: Rimfire Minerals Corporation, TSX-V:RFM, is pleased to announce that in partnership with Northgate Minerals Corporation, TSX:NGX, drilling has commenced at its new gold discovery on the Boulevard Property. The Boulevard Property is located approximately 135 kilometres south of Dawson City, Yukon. Gold bearing mineralization, including 7.04 g/t gold over 6.0 metres, was discovered in two of three trenches over a 300 metre trend (see Rimfire news release PR08-12, August 20, 2008). The diamond drilling program will consist of 4 to 6 holes averaging 150 metres in length and is expected to be completed by mid-October.

The current program was initiated after this summer's discovery of gold-bearing mineralization in trenches testing anomalous arsenic-antimony-gold soil geochemistry at the Boulevard. Chip sampling from the first trench (TRBV08-01) yielded 7.04 g/t gold over 6.0 metres. One hundred metres southeast, trench TRBV08-02 returned 6.43 g/t gold over 2.0 metres. Gold mineralization is hosted in strongly sericite-clay altered schists with disseminated pyrite, arsenopyrite, stibnite and specular hematite that envelopes quartz and massive stibnite veins. Additional soil sampling undertaken in conjunction with trenching has now expanded the target to an area of 2.0 by 0.4 kilometres. Drilling will aim to test mineralization encountered in the trenches at depth. Soil sampling and a reconnaissance IP geophysical survey has commenced to help expand the target, as well as refine drill hole locations along trend.

This program is being conducted under an exploration alliance agreement with Northgate Minerals signed in December, 2005. The Boulevard Property is held jointly by Rimfire and Northgate, with each company having funded the initial $330,000 in targeting and exploration that led to staking of the property. To date, Northgate has funded approximately $435,000 of the required $1.5 million in exploration expenditures to earn an additional 10% interest (for a total of 60%) in the property.

Rimfire and Inmet Commence Drilling at Grizzly

Vancouver, BC -- Sept 8, 2008: Rimfire Minerals Corporation, TSX-V:RFM, is pleased to announce that in partnership with Inmet Mining, it has commenced the second phase of fieldwork at the Grizzly Property in northwest British Columbia. Phase 2 will consist of 1500 metres of drilling aimed at targets defined by the first phase program which included prospecting, mapping, soil geochemistry and a 32 line kilometre Induced Polarization (IP) survey. The drill program will test the Grizzly showing and targets on the Mirko Grid. The Grizzly copper-gold porphyry target shows a number of similarities to Teck Cominco/Novagold's Galore Creek deposit, including the volcanic host rocks, associated magacrystic syenite porphyries, regional magnetic signature and style and composition of hydrothermal alteration and mineralization. The Grizzly Property is approximately 50 kilometres east of the Galore Creek project and within four kilometres of the partially completed Galore Creek access road.

Previously reported mineralization from trenches at the Grizzly Showing returned results which included 38 metres averaging 0.74% copper and 1.1 g/t gold from continuous chip sampling. This copper and gold mineralization is reflected in the 2008 IP survey as chargeability values of 10 to 15 mV/V. This geophysical signature defines an area of potential copper -- gold mineralization that is 750 metres wide by 400 metres long and open to the northeast, east and to depth. This area of high chargeability is also coincident with a one square kilometre copper, gold and molybdenum soil geochemical anomaly which taken together define a compelling target. The 1500 metre drilling program directed at targets on both the Grizzly showing and the Mirko grid will be financed by Inmet Mining.

"We are very pleased that the IP has responded by highlighting and characterizing the surface mineralization at the Grizzly Showing," stated Jason Weber, P.Geo., President and CEO. "The knowledge we have gained by modeling the known mineralization with IP allows us to target aggressively within the large area of positive IP response in particular where those same areas coincide with strong copper and gold geochemistry."


The Mirko Grid
Soil sampling on the Grizzly property identified zones with anomalous copper, gold and molybdenum geochemistry two kilometres to the northwest of the Grizzly showing. This area (the Mirko Grid) is interpreted to be geologically similar to the Grizzly Showing based on airborne magnetic data and sparse outcrop; however the source of the soil anomalies is largely unknown due to poor exposure. Three consecutive 400 metre-spaced IP lines identified 100 to 200 metre wide zones with anomalous chargeabilities coincident with some of the highest molybdenum, copper and gold values in the Mirko soil geochemical anomaly. This pattern of coincident IP chargeability and anomalous soil geochemistry also provides the basis for a drill targets on the Mirko Grid.

The Grizzly project is being explored through a partnership with Inmet Mining announced January 2008. Under the terms of the agreement, Inmet Mining may earn up to a 60% interest in the property by funding at least $5 million in exploration at the Grizzly over four years. For additional information please see the press release dated January 31st, 2008.

Rimfire/Northgate Make Gold Discovery at Boulevard, Yukon

--------------------------------------------------------------------------------

PR08--12

Vancouver, BC -- August 20, 2008: Rimfire Minerals Corporation ("Rimfire") is pleased to announce the discovery of gold mineralization made during a trenching program conducted with partner Northgate Minerals Corporation at the Boulevard Property in Yukon Territory. The Boulevard Property is located approximately 135 kilometres south of Dawson City, Yukon. Gold bearing mineralization, including 7.04 g/t gold over 6.0 metres, was encountered in two of three trenches spaced 300 metres apart. A 1000 metre diamond drilling program to test this new discovery will commence September 1 of this year.

Chip sampling from the first trench (TRBV08-01) yielded 7.04 g/t gold over 6.0 metres. One hundred metres southeast, trench TRBV08-02 returned 6.43 g/t gold over 2.0 metres. A third trench located 200 metres northwest of trench TRBV08-01 appears to have been located off trend. Gold mineralization is hosted in strongly sericite-clay altered schists with disseminated pyrite, arsenopyrite, stibnite and specular hematite that envelopes quartz and massive stibnite veins. The work program, completed in July, targeted anomalous arsenic-antimony-gold soil geochemistry. Additional soil sampling undertaken in conjunction with trenching has now expanded the target to an area of 2.0 by 0.4 kilometres.

"This mineralization doesn't outcrop. It is a blind discovery that is the result of solid execution of classic grassroots exploration techniques," stated Jason Weber, President and CEO of Rimfire Minerals. "Together with Northgate, we have advanced the Boulevard from concept to discovery and we now look forward to the September drill program where we will test the extent of this mineralization."

This program was conducted under an Exploration Alliance with Northgate signed in December, 2005. This alliance targeted "Pogo-style" intrusion-related gold deposits in an area fitting the model criteria and possessing placer gold deposits without a known bedrock source. The Boulevard area was selected from a much larger regional compilation and reconnaissance silt sampling program that led to the identification of anomalous gold and pathfinder elements in creeks draining the Boulevard. Detailed soil sampling in 2007 outlined the multi-element geochemical anomaly that was the focus of the recent trenching program.

In light of these positive results, Rimfire and Northgate have added 96 claim units to the property and a follow up program is planned for early September. This program will consist primarily of diamond drilling with four to six holes (averaging 150 metres in length) to test the continuity of the mineralization at depth and on strike. Prior to drilling, reconnaissance IP geophysical survey lines will be completed to determine if IP will be an effective targeting tool. As well, auger soil sampling will be conducted over certain portions of the existing grid to recover higher quality samples from areas where permafrost and an ash layer have masked soil geochemical response.

The Boulevard Property is held jointly by Rimfire and Northgate, with each company having funded the initial $330,000 in exploration that led to staking of the property. To date, Northgate is has funded approximately $435,000 of the required $1.5 million in exploration expenditures to earn an additional 10% interest (for a total of 60%) in the property.

Rimfire Partners with Northgate to Explore Australia's Stawell Gold Trend

--------------------------------------------------------------------------------

PR08-11

Vancouver, BC -- July 28, 2008: Rimfire Minerals Corporation ("Rimfire") is pleased to announce a new exploration partnership with gold-producer Northgate Minerals Corporation (NGX-TSX), which grants Rimfire an option on its Stawell Corridor gold exploration properties in the State of Victoria, Australia. Northgate, through its 2008 acquisition of Perseverance Corporation Ltd., acquired a dominant claim position in the Victoria Goldfields, host to over 50 million ounces of gold in both alluvial and hard rock reserves and production.

"With this agreement, we are building on an established relationship," said President and CEO, Jason Weber. "It is a terrific opportunity that became available to us because Northgate's focus is on exploration around their two operating mines, allowing us to advance their outside targets in the corridor."

Chris Rockingham, VP of Exploration and Business Development for Northgate stated, "From Northgate's perspective, choosing Rimfire as a joint venture partner was easy. They have proven to be very capable operators in our Canadian Joint Ventures and the Stawell Corridor land package is ideally suited for their grass roots exploration skill set."

Highlights of this agreement include:

• The opportunity to explore a highly productive gold belt in a politically stable jurisdiction.
• The land position is coherent, encompassing much of the Stawell Corridor. The Stawell Corridor itself is well defined with Northgate's high grade Stawell Gold Mine (SGM) at its core.
• Excellent greenfield exploration opportunities. The exploration model for the corridor has been extensively studied, providing exploration criteria at both the regional and detailed scales. Rimfire will have access to Northgate's SGM which will help build a better understanding of the geological model and improve Rimfire's exploration effectiveness.
• High quality targets with convincing similarities to SGM exist in the land package being made available to Rimfire. Previous work programs were well designed, identifying numerous targets that have yet to be brought to the drill-ready stage, however, insufficient resources were available to the predecessor company to conduct systematic greenfields exploration of the entire land package.
• The deal is structured similar to other Rimfire/Northgate arrangements in which Rimfire undertakes to advance exploration to the point where drill targets are defined, at which time Northgate can take over funding of exploration, earning a larger percentage in the property for doing so.

The Stawell Corridor is a 240 km long belt bound by the Congee and Moyston faults and cored by Northgate's 5 million ounce Stawell Gold Mine (20 Mt at 8 g/t gold). Mineralization consists of gold-bearing quartz veins in ferruginous (iron-rich) sediments associated with basalt centres. This deposit has been studied extensively, resulting in the identification of large-scale characteristics that can be used in the exploration for similar deposits elsewhere in the district. Geophysical techniques such as gravity and magnetics surveys have proven effective in targeting basalt centres and granites associated with mineralization. These techniques will be important in evaluating the rest of the Stawell Corridor and refining targets for drilling.

Rimfire will be exploring three licences, totaling 120 km of the corridor length, representing all ground outside of a buffer around the Stawell Gold Mine. In addition to greenfields opportunities, more advanced targets exist including the 10 kilometre-long Murtoa target, which surrounds the Kewell gold resource. The Kewell resource, which Northgate has opted to exclude from this agreement, is reported to contain a historic 100,000 ounces of gold at 6 g/t gold and has been defined by 25 drillholes. Additional targets include kilometre-scale gravity anomalies that have been confirmed through drilling to reflect basalt centres at depth, with coincident gold and pathfinder element geochemical anomalies on surface. Rimfire has commenced a compilation of all the available data to plan field work for this fall.

Under the agreement, Rimfire agrees to conduct exploration to maintain the licenses in good standing for the current year (approximately $370,000). Rimfire can then elect to conduct further exploration on any or all three of the licenses, earning a 50% interest on each by spending $500,000 per license over two years. Northgate then has the option on each license to: 1) carry out the next $1.5 million to earn back a 10% interest (total 60%) and another 10% by reaching a production decision; 2) not participate and allow Rimfire to earn a 100% interest in the property by spending, or causing to have spent, an additional $2 million over 4 years; or 3) participate in a 50/50 joint venture.

NEW YORK (MarketWatch) -- Gold futures reversed earlier losses on Tuesday, as the dollar fell against major counterparts on bleak U.S. economic data, while traders reconsidered the importance of an expected sale of gold reserves by the International Monetary Fund.
Gold for April delivery gained $8.40 to end at $940.50 an ounce on the New York Mercantile Exchange.
Gold futures had fallen Monday after a senior Treasury official said the U.S. supports the proposed sale of part of the gold reserves held by the IMF.
"But there is an understanding that the IMF issue is minor at best," said Brien Lundin, president at Jefferson Financial. "The sale still needs congressional approval, which remains doubtful, and the amount would be minor anyway."
"In the past, IMF gold sales have typically marked a buying opportunity for people who had missed a rally," Lundin said.
A lower dollar also boosted the appeal of bonds. Gold, as many commodities, is denominated in dollars and a lower U.S. currency makes it more affordable in other currencies.
The dollar fell against major currencies, after an unexpectedly sharp rise in the producer price index and a plunge in consumer confidence heightened fears that the U.S. economy may end up in the grip of stagflation. Read Currencies.
For gold, long-term fundamentals remain favorable, Lundin said.
"The long-term downtrend of the dollar losing favor, expectations that the [Federal Reserve] will cut interest rates by at least another half a point, global economies are a bit stronger than the U.S. economy and that's boosting demand pressures on commodities and [inflation]," he said.

NEW YORK (MarketWatch) -- Gold futures dropped Monday after a senior Treasury official said that the U.S. supports the proposed sale of a part of the gold reserves held by the International Monetary Fund.
Gold for April delivery fell $7.30 to end at $940.50 an ounce on the New York Mercantile Exchange.
"The support that the U.S. is now apparently lending to the recently proposed IMF gold sales -- which is a departure from its previous negative stance on such sales -- is causing a few to take profits," said Jon Nadler, senior analyst at Kitco Bullion Dealers, in a research note.
"It is believed that the sales, slated to commence in April, might bring some 400 tons of gold out of the IMF vaults and onto the market," Nadler said.
David H. McCormick, under secretary for international affairs at the Treasury Department, said Monday that the Bush administration considers the plan to sell 12.9 million ounces of gold as "probably the most viable" option to ensure the long-term funding of the IMF, Dow Jones Newswires reported Monday.
McCormick said that there is "some confidence that there will be some support for this" among members of the U.S. Congress and "broad-based support" for the plan among members of the Group of Seven industrial nations, according to the report.
The IMF ranks as the number three holder of gold in reserves, after the U.S. Federal Reserve and Germany's Bundesbank.
The U.S. Congress could block the administration's initiative, said Marc Chandler, currency strategist at Brown Brothers Harriman & Co., in a research note.
"Previously Congress opposed IMF attempts to sell gold in both 1999 and 2005, but
McCormick hinted at having Congressional support now," Chandler said.
"The price of gold fell on the news, which also corresponded to the slightly better than expected existing home sales in the US and a bounce in the U.S. dollar," he said.
Dollar gains
On the currency markets, the dollar got a boost against major rivals Monday, after U.S. home-sales data were not as downbeat as many investors had expected. See Currencies.
The dollar index, which measures the greenback against a basket of six major currencies, was at 75.536, up from 75.480 before the data and 75.514 in Friday's late U.S. trading.
Resales of U.S. homes and condos dropped 0.4% in January to a seasonally adjusted annualized rate of 4.89 million, even as inventories of homes on the market rose, the National Association of Realtors reported Monday.
It was the lowest sales pace since the real estate group began tracking combined sales in 1999 but was stronger than the 4.80 million pace expected by economists surveyed by MarketWatch. See Economic Report.
On Friday, gold finished down $1.40 but chalked up a weekly gain of $41.70. On Thursday, gold surged to a record high of $958.40 an ounce.
Thursday's gains pushed gold toward overbought territory, as borne out by gold appearing to struggle to rally to close out the week, said James Moore, an analyst at TheBullionDesk.com.
However, "the speed with which the metal recovered from its dip suggests plenty of players remain on the sidelines keen to buy dips, and that rate-cut expectations and rising inflationary pressures will continue to draw investment demand," Moore said in a research note

Copper-Gold Mineralization Intersected in Wernecke Breccia JV Drilling

--------------------------------------------------------------------------------

Press Release 08-01

Vancouver, BC - January 9, 2008: Jason Weber, President and CEO of Rimfire Minerals Corporation reports that results from drilling at the Hoover Property have been received from the Wernecke Breccias Project, a joint venture with Fronteer Development Group Inc. Exploration conducted throughout the 2007 field season targeted iron oxide copper-gold-uranium targets and stand-alone uranium targets on the Joint Venture's 373-sq-km land package in the Wernecke Mountains of Canada's north-central Yukon Territory.

The latest holes continue to expand the limits of known copper-gold mineralization at the Hoover Property. New drilling highlights include:
1.84% copper and 0.53 grams per tonne gold over 17.3 metres in HV07-27.
0.56% copper and 0.16 grams per tonne gold over 45.5 metres in HV07-27.
1.20% copper and 0.48 grams per tonne gold over 7.9 metres in HV07-26.
Mineralization at the Hoover Property has been intersected in 11 widely spaced holes and approximately 500 m of strike length. This mineralization remains open for expansion to the north and south as well as at depth. Anomalous copper-in-soil geochemistry has been detected as far as 800 m to the south along strike from the most southerly drill hole.

Additional Copper-Gold Results From Wernecke Breccia JV Drilling

--------------------------------------------------------------------------------

PR08-02 Vancouver, BC -- January 17, 2008: Jason Weber, President and CEO of Rimfire Minerals Corporation reports additional results from drilling at the Hem and Pagisteel Fault prospects of the Wernecke Breccias Project, a joint venture with Fronteer Development Group Inc. Exploration conducted throughout the 2007 field season targeted iron oxide copper-gold-uranium targets and stand-alone uranium targets on the Joint Venture's 373-sq-km land package in the Wernecke Mountains of Canada's north-central Yukon Territory.
Highlights from the Pagisteel Fault and HEM prospects are:
2.57% copper and 0.97 grams per tonne gold over 6.10 metres in PG07-01 at the Pagisteel Fault.
0.69% copper and 0.17 grams per tonne gold over 9.33 metres in UT07-11 at HEM.
0.36% copper and 0.18 grams per tonne gold over 8.37 metres in UT07-12 at HEM.

Hole PG07-01 is the first to test a regional fault structure associated with a 4-km long trend of soil and rock geochemistry anomalous in gold and copper at the Pagisteel Fault Prospect. This hole intersected several faulted zones interleaved with sections of metasomatized sedimentary rock with locally disseminated to semi-massive chalcopyrite and pyrite.
At Hem, two holes spaced 200 metres apart were drilled to test a broad low-grade copper intersection encountered by previous workers in 1995 drilling. The holes cut variably (silica-potassium-feldspar-hematite) altered siltstone and potassium feldspar-albite-chlorite-sericite altered Wernecke breccia and zones of specularite-carbonate-magnetite-chalcopyrite veining.

Williams Project Update

--------------------------------------------------------------------------------

PR08-03 Vancouver, BC -- January 31, 2008: Jason Weber, President and CEO of Rimfire Minerals Corporation reports final results from the 2007 exploration of the Williams Property, located 150 kilometres southeast of Dease Lake, BC. This work, funded by Arcus Development Group Inc., consisted of mapping, prospecting and rock, silt and soil geochemical sampling to evaluate new claims staked in 2006. Ground work was also undertaken at the T-Bill high-grade gold target to refine targets for drilling, and at the GIC porphyry copper-gold prospect. Soil geochemical sampling led to the identification of the LN anomaly, a large molybdenum, copper+/-gold-in-soil geochemical anomaly immediately east of the GIC prospect.

Arcus has informed Rimfire that it does not intend to continue exploration of the Williams Property. Rimfire will retain 100% of the property, which includes two drill-ready targets at the T-Bill and GIC prospects. In keeping with Rimfire's business model, management will be seeking a partner to advance both prospects.

T-Bill Prospect

The focus of the 2007 program at the T-Bill was to confirm the orientation of quartz-carbonate-arsenopyrite veins in order to refine targets for subsequent drilling. This program included hand trenching in select areas to expose veining that previous workers had intersected in drilling. Eighteen historic holes have been drilled within a 900 by 500 metre area to date resulting in 11 separate 2.0 metre intersections in excess of 12.0 g/t gold, including 35.0 g/t gold and 24.8 g/t over 2.0 metres. Potential for large low-grade gold style targets is evidenced by intersections from the same area that include 1.1 g/t gold over 75 metres (true width). Hand trenching of the T-Bill veining confirmed management's interpretation that the vein swarm is steeply dipping with a northwest/southeast strike.

GIC Prospect

Previous programs at the GIC Prospect include drilling in 2006 that identified porphyry style alteration and pyrite dominant mineralization coincident with an Induced Polarization (IP) chargeability high anomaly. The 2007 program focussed on unexplored jarosite gossans east of the area drilled in 2006, and led to the identification of the LN Anomaly, a 450 by 900 metre molybdenum, copper+/-gold-in-soil anomaly (Mo > 16 ppm, Cu > 129 ppm). The anomaly, which remains open to the east, is coincident with an airborne magnetic high.

"We were successful in verifying the orientation of veining at the T-Bill Prospect and determining that the porphyry-style hydrothermal system at the GIC extends outside of the area investigated by drilling in 2006. We now have excellent drill targets at both prospects," stated Mark Baknes, VP Exploration for Rimfire. "Molybdenum-copper soil geochemistry may be vectoring us from pyrite (iron) dominated mineralization to copper, gold and molybdenum-rich mineralization east of the GIC. At the T-Bill, we now have much more certainty in the orientation of high-grade gold veining which will allow us to systematically test these veins by drilling. We will be seeking a partner to test these two targets."

The 2007 work program was conducted under the direction of Henry Awmack, P.Eng., of Equity Engineering Ltd., a Qualified Person for the purpose of National Instrument 43-101. Assays were completed by ALS Chemex Labs of North Vancouver, BC.

Inmet Options Rimfire's Grizzly Copper-Gold Project

--------------------------------------------------------------------------------

PR08-04

Vancouver, BC -- January 31, 2008: Jason Weber, President and CEO of Rimfire Minerals Corporation is pleased to report that Inmet Mining Corporation has signed a Letter Of Intent (LOI) to an option on the Grizzly Property, in northwestern British Columbia. Under the terms of the agreement, Inmet can earn a 60% interest by funding at least $5 million in exploration at the Grizzly over four years, including $800,000 in the first year. Inmet will make staged cash payments totalling $250,000 over the earn-in period, including $50,000 upon signing of the LOI.

The Grizzly Property is approximately 50 kilometres east of the Galore Creek project and within four kilometres of the partially completed Galore Creek access road. The Grizzly copper-gold porphyry target shows many similarities to Galore Creek, including its geological setting, volcanic host rock geochemistry, regional magnetic and gravity geophysical signatures, hydrothermal alteration and metal signature. Rimfire crew resampled old trenches in 2006, yielding 38 metres averaging 0.74% copper and 1.1 g/t gold from a continuous chip sample. The Grizzly showings occur within a one square kilometre copper, gold and molybdenum-in-soil geochemical anomaly. A second area of anomalous copper, gold and molybdenum soil geochemistry (the Mirko Grid) lies approximately 2 km northwest. The cause of this anomaly has yet to be investigated.

"We are looking forward to working with Inmet to advance the Grizzly Project," stated Jason Weber, President and CEO of Rimfire Minerals. "Inmet's exploration strategy focuses on the discovery of world class copper deposits. We are very pleased that their team feels that the Grizzly may help them achieve their goal."

Preliminary exploration plans for 2008 include a comprehensive program of geological mapping, Induced Polarization (IP) geophysics, and trenching to provide drill targets by year-end.

Tide Project Update -- Drilling Expands 36 Zone

--------------------------------------------------------------------------------

PR08-05

Vancouver, BC -- February 19, 2008: Jason Weber, President and CEO of Rimfire Minerals Corporation is pleased to report final results from exploration conducted at the Tide Property in 2007. The road accessible Tide Property is situated 36 km north of the port of Stewart, BC, within the Stewart-Sulphurets corridor. The 2007 program was funded by American Creek Resources Inc., and consisted of 1835 metres of drilling in eight holes, detailed mapping and 318 metres of channel sampling targeting bulk-tonnage style gold mineralization.

Rimfire is targeting the Tide due to its large soil and silt geochemical anomalies, the extent of its precious metal mineralization, its proximity to favourable infrastructure and its location within the Stewart-Sulphurets corridor. Recent exploration in the Stewart-Sulphurets gold camp has reportedly expanded the resources at deposits such as Mitchell (13.1 million ounce gold and 2.2 billion pound copper resource at an average grade of 0.72 g/t gold and 0.18% copper -- Seabridge Gold) and Snowfield (3.0 million ounce gold resource at an average grade of 1.5 g/t gold -- Silver Standard Resources).

Every hole drilled in the 2007 program returned anomalous gold values over large widths, including Tide07-13, which averaged 0.49 g/t gold over the entire 207 metre length of the hole and Tide07-14 which averaged 0.33 g/t gold over the entire 247 metre length. Highlights include Hole Tide07-13, aimed at testing the southern extents of the 36 Zone, which included two separate intervals of 43.6 m of 1.0 g/t gold and 22.5 m of 0.94 g/t gold. Drilling at the 36 Zone was conducted on four sections spaced approximately 50 metres apart. Two holes were completed at the Northpit target and one hole at the Riptide target located 375 and 600 metres east of the 36 Zone, respectively.

"The 36 Zone is a compelling bulk tonnage-style gold target," stated Mark Baknes, VP Exploration. "Our previous metallurgical studies show that this mineralization is amenable to leaching. Our best results in drilling plus all of our surface work, including fracture density studies and surface chip sampling, suggest that the next test of the 36 Zone should be to the north and south."

The 36 Zone was discovered in 2005 when a single drill hole intersected 129.4 metres averaging 1.0 g/t gold including a 39.6 metre interval of 1.9 g/t gold. To date, drilling at the 36 Zone has been confined to a 250 by 750 metre area within the 600 by 2500 metre Crest gold-arsenic soil geochemical anomaly (>500 ppb gold in talus fines). The 2007 drilling program successfully extended the 36 Zone mineralization 100 metres to the north and 150 metres east. Further to the east at the Riptide zone, mineralization appears to be confined to narrower structures.

In conjunction with drilling, field crews conducted a ground program consisting of chip sampling and detailed geological and fracture mapping. This data, in conjunction with fracture density data will be used to target 2008 holes at the 36 Zone, with a focus on areas to the south of the current drilling. A plan map of the 36 Zone with 2007 drill hole locations can be viewed at www.rimfire.bc.ca./s/tide.asp.

The 2007 Tide program was funded by American Creek Resources Ltd., under the terms of an option whereby American Creek can earn an additional 9% (total 60%) interest in the joint venture by funding $3.5 million in exploration by 2010. American Creek is the project operator. This news release has been reviewed by Mark Baknes, M.Sc., P.Geo., a Qualified Person for the purpose of National Instrument 43-101. Assays were completed by ALS Chemex Labs of North Vancouver, BC.
