Farallon Announces First Quarter Financial and Operating Results

$6.2 Million Net Earnings
25m lb of Zinc Produced at a Total Cash Cost1 of $0.38/lb payable zinc

May 12, 2010, Vancouver, BC - Farallon Mining Ltd. ("Farallon" or the "Company") (TSX:FAN) announces its financial and operating results for the three months ended March 31, 2010. Currency amounts are stated in United States Dollars, unless otherwise noted.

The Company's G-9 mine produced a record 25.0 million pounds of zinc and 2.1 million pounds of copper in concentrates at a total cash cost1 of $0.38/lb of payable zinc. Farallon reported net earnings of $6.2 million and the Company generated $6.0 million in cash from operations before changes in non-cash working capital.

"The G-9 mine has increased production every quarter since production began in the first quarter of 2009" said President and CEO Dick Whittington. "Quarterly production has steadily increased from 1,180 tpd to 1,650 tpd, a 40% increase over the last 15 months. With improvements in throughput to over 1,900 tonnes per day in March and April and metallurgical improvements being made, the G-9 mine is now providing steady cash flow and a base from which we can deliver on our objective of becoming a mid-tier, multi-mine company."

Highlights for the three months ended March 31, 2010 ("Q1") compared to the three months ended December 31, 2009 ("Q4") are as follows:

Financial

* Operating earnings of $9.1 million and net earnings of $6.2 million, up from operating earnings of $3.9 million and net earnings of nil in Q4.

* Cash flow from operations before changes in non-cash working capital of $6.0 million, up from $2.2 million in Q4.

* Gross revenues of $37.6 million, up from $32.3 million in Q4.

* Non-GAAP Adjusted EBITDA1 of $9.0 million, up from $4.5 million in Q4.

* Total cash cost per payable pound of zinc1 of $0.38/lb (including $0.31/lb for the month of March 2010), down from $0.44/lb in Q4.

* Working capital of $18.2 million at March 31, 2010, up from $14.9 million at Dec 31, 2009.

Operations

* Processed 152,178 tonnes of ore (average throughput 1,691 tonnes per day - "tpd") grading 9.1% zinc, 1.1% copper, 174 g/t silver and 2.5 g/t gold. Increased throughput rates for the month of March 2010, processing 59,715 tonnes of ore for an average rate of 1,926 tpd or 128% of design.

* Produced 23,365 tonnes of zinc concentrate and 6,952 tonnes of copper concentrate, containing an estimated 25.0 million pounds of zinc, 2.1 million pounds of copper, 420,911 ounces of silver and 4,322 ounces of gold from the G-9 mine.

* Sold approximately 22,420 tonnes of zinc concentrate grading 48% zinc and 9,480 tonnes of copper concentrate grading 14% copper. Payable metals contained in concentrate were 20.0 million pounds of zinc, 2.7 million pounds of copper, 336,000 ounces of silver and 4,106 ounces of gold. Realized metal prices on sales of $0.99/lb zinc and $3.23/lb copper.

* Given the success of increasing mill throughput to over 1,900 tpd in March and April, the Company is revising the scope of the Mill Expansion project to determine the maximum throughput that can be obtained within the approved capital budget of $5.3 million. However, the Company continued with procurement of additional regrind and flotation equipment for the Mill Expansion Project. The project was originally designed to increase mill capacity from 1,500 tpd to 2,000 tpd by July 2010.

Exploration

* Continued exploration drilling at Campo Morado with two surface drills and one underground drill operational as part of a $5.4 million program for 2010.

* Updated the G-9 mineral resource estimate as at December 31, 2009 which includes 3.0 million tonnes of Measured and Indicated Resources at 9.4% zinc and 1.3% copper as well as 0.9 million tonnes of Inferred Resources at 9.2% zinc and 1.1% copper (at a 3.0% zinc cut-off)2.

* Upgraded a portion of the mineral resources as at December 31, 2009 to mineral reserves, including 2.0 million tonnes of Proven and Probable Reserves at 10.0% zinc and 1.34% copper2.

* Initiated an engineering study on the treatment of El Largo, Naranjo and El Ray deposits. The study is investigating the mining and processing of 4.9 million tonnes of Indicated Mineral Resources at 6.4% zinc, 2.1 g/t gold and 165 g/t silver (at a 5% zinc cut-off grade) with the existing mining equipment and processing facilities2.

* As part of its preliminary assessment of the potential for high grade gold zones being present below the main zinc orebodies, the Company announced on April 21, 2010 the discovery of three distinct high-grade gold zones outside the current mineral resources (at a 5% zinc cut-off grade) at the G-9 mine. These zones contain estimated Inferred Mineral Resources of 225,038 tonnes grading 8.6 g/t gold and 407 g/t silver (at a 5 g/t gold cut-off grade)3.

Dick Whittington said "The exploration program at Campo Morado is continuing on three fronts. First, the Company has two surface drills exploring north of the Abajo zone, targeting new lenses on the Abajo horizon. Second, we continue to utilize underground drilling to delineate new high-grade zinc resources in and around the existing G-9 mining operations. Third, the program to evaluate and expand upon the newly announced gold zones is advancing."
