Delta Mining and Exploration Corp. (OTC:DMXP) is a mineral exploration company that controls 6 properties totaling 7,554 acres (approximately 11 sq. miles) in Montana. The properties are all located over what management considers to be some of the most prospective diamond exploration terrain in the United States.

Delta has experienced significant technical success since its start-up in 1997. For example, Delta has discovered the first in-situ microdiamond ever found in Montana on its Homestead Kimberlite, southeast of Lewistown. The Company also controls part of the Three Buttes Kimberlite where initial exploration has shown The Three Buttes Kimberlite to host typical diamond indicator minerals – a major step toward finding the presence of economic diamonds – including pyrope (garnet), chromite and clinoprroxene.

An aggressive regional exploration program has the potential to discover additional kimberlite or lamproite pipes in this under-explored area to the south of known commercial diamond bearing kimberlites in Saskatchewan and Alberta, Canada.

Delta seeks to increase growth for its investors not only by testing its extensive portfolio of diamond exploration properties but also by acquiring additional diamond properties. Delta will focus on identifying and developing strategic alliances with major mining companies as well as joint ventures to develop the properties and finance additional exploration.

In addition to the highly prospective diamond properties Delta controls, they also control a gold property with great potential.

Primary (as opposed to secondary or alluvial) diamond deposits are mined from either kimberlite or lamproite rock-types which originate deep beneath the earth’s crust. Diamonds exist at more than 100km depth within the earth’s mantle and are transported to the earth’s surface by extremely rapid volcanic eruptions (“diatremes”), which form these rare kimberlite and lamproite pipes.

Kimberlites host the most common type of commercial diamond deposits. Approximately 12% of all known kimberlites contain diamonds, while only 2% contain economic quantities. Lamproites are extremely rare: of the 25 known lamproites in the world, about 25% contain diamonds. The most famous lamproite is the Argyle Pipe in Western Australia, which produces about 30% of the world’s diamonds.

Although very rare, the risk-versus-reward profile for exploration success in the diamond exploration business can be spectacular. For example, the Jwaneng kimberlite diamond deposit in Botswana contains diamonds with a gross value of around $75 billion. At Ekati in the Lac de Gras region of the Northwest Territories of Canada, the deposits have a gross mineable resource worth over $15 billion and produce over 10% of the world’s diamonds

Spider Resources Inc.: President's Update for December 2006
12/7/2006

TORONTO, ONTARIO, Dec 07, 2006 (MARKET WIRE via COMTEX News Network) --
Now that we are well into the fall/winter season, which is typically a fairly active time for the junior mining sector, it is my pleasure to update shareholders on the recent activity of Spider Resources Inc. (TSX VENTURE: SPQ), and our plans for the immediate future. Through several years of progress at the various property interests that we have controlled along with our joint venture partner, we've reached the point where important decisions need to be made so we can most efficiently maximize the discovery value for our projects in the future. Spider has been uncharacteristically quiet on the news front for quite some time, as management has been strategizing Spider's future over the past few months.

Exploration is an expensive endeavor with an uncertain outlook. Our previous strategy for approximately the last decade has been to form alliances with partners, to defray Spider's funding requirements in exchange for earning and maintaining an interest in various projects. This strategy has contributed to the successes we were able to achieve on the exploration front. All of our active projects to date have involved some form of partnership with KWG Resources Inc. As part of the reorganization of our alliance with KWG (see press release dated May 15, 2006) we have revised our partnership agreement to enable each company to further explore those projects that are of greatest interest, without requiring the other partner to agree to participate. This allows each party, to progress only those projects in which they have the greatest interest. We are required to bear the costs to continue to advance the projects that Spider has selected to advance. We must now determine which of them has the greatest potential for development. Spider's continuing strategy is to minimize expenditures where possible while maintaining the maximum interest in specific projects which have the strongest likelihood of future success.

The removal of the funding constraints for all the projects allows greater flexibility with exploration expenditures dedicated to specific projects. Additionally the option to secure alliances with new joint venture partners without the participation of KWG is a valuable tool missing in the past. The new arrangement with KWG allows Spider to enter into discussions with others on projects that Spider has elected to advance. As a result, the company announced on July 24th 2006 a new joint venture with Renforth Resources Inc. (formerly Wycliffe Resources Inc.). This arrangement will allow Renforth to earn an interest at the Kyle Lake Project by funding the next round of exploration work.

Prior news releases, have disclosed successful discovery of diamond-bearing kimberlite pipes in five separate occurrences within the Kyle Project. This project now warrants bulk sampling of the kimberlites, in order to complete a diamond size distribution curve analysis for each of these discoveries. The cost of each bulk sample is estimated at between $500,000 to $600,000. We already have collected approximately six tonnes from the Kyle Lake 1 and Kyle 3 kimberlites, with encouraging results.

At Kyle 2 Renforth has recently completed a core drilling program to initiate the collection of approximately five tonnes of sample material, in order to start the diamond test-work. Two holes were completed earlier this fall, and continued assessment of this kimberlite is scheduled for later this year and early next. Renforth also advises that work will commence on the Kyle 4 and Kyle 5 kimberlite occurrences early next year as their plan is to collect up to 5 tonnes of kimberlite from these as well. The initial objective for their exploration program on Spider's properties will be to analyze the diamond content of each of the 5 kimberlites to determine which of the kimberlite deposits has the best potential economic merit prior to funding larger scale test work at any of the sites. In addition to the much needed exploration funds to advance this project, Renforth contributes to the joint venture 39 kimberlite targets covered by 449 claim units. Each of these 39 kimberlite prospects will be prioritized and incorporated into a regional project in early 2007, this work is underway. It was Spider's work and vision, over a decade ago, along with the activities of De Beers that led to this new diamond province in Ontario's Lowlands. Other diamond explorers have now become active, or are simply maintaining claims in the immediate Kyle Diamond Area, including; De Beers in Joint Venture with Trigon Explorations, Southernera, Metalex, Probe, and Northern Shield. Renforth has agreed to contribute up to $6 million at the rate of $2 million per year over the next three years, in order to earn a 55% interest in the project, ensuring that the funding is in place to continue the exploration process on Spider's properties in this emerging diamond area of Canada.

This deal has added value for our shareholders, as Spider Resources will retain an exposure to the James Bay diamond play without any funding requirements At any time and at our election, Spider can opt to support or contribute to the exploration efforts of Renforth, contributing up to $5.92 million to reach 30% interest in this project, leaving KWG with the remaining 15% interest. Elsewhere in the general region, other companies are actively performing similar testing on their kimberlite, most notably Metalex on their nearby T1-1 kimberlite. At the nearby (100 km to the east) Victor Diamond project, DeBeers has decided to proceed with a development plan and are now fully permitted to build Ontario's first diamond mine at a capital cost of close to $1 billion, with start up currently scheduled for 2008. In just two years Ontario will be established as a diamond producing province, and De Beers' decision to go forward underlines our commitment to remain active with our diamond exploration efforts in the district.

We also continue to retain an interest in the five diamond bearing kimberlite pipes that have been discovered in the MacFayden Project with partner KWG. KWG has laid out plans to survey the perimeter of the property and bring the claim group to lease. Additionally, they have recently signed an exploration agreement with Attawapiskat First Nation. Kimberlite drill definition followed by bulk sampling of some of the MacFadyen kimberlites is planned for 2007. Spider will be not be required to contribute any funding for this program, but may need to contribute in the future, to maintain our one-third interest in the project, once KWG has expended $3.83 million specifically on the MacFadyen properties.

Continuing with our diamond projects, the diamond bearing outcrops that we have discovered near Wawa, Ontario continue to represent a challenge, in that the highest distribution of diamonds has been determined to be contained in isolated xenolith nodules within the much larger matrix of host rock. From surface outcroppings we estimate that xenoliths constitute approximately 10 - 20% of the entire rock mass. Diamond drilling this occurrence will give us a better understanding of the xenolith content, as the xenoliths content can be physically measured and converted to a percent by volume. We are continuing to work to identify a process to release the diamonds from the xenolith. This would enable targeting the higher content xenolith bearing portions of the geological structure and allow evaluation of the occurrence and perhaps lead to a bulk test.

At McFauld's Lake, the company has a very encouraging base metals (copper and zinc) discovery prospect. Our relatively shallow drill programs to date have outlined several well mineralized massive sulphide zones....///..++++++++++++++++++++++++++++++++++++//..The TSX Venture Exchange does not accept responsibility for the adequacy or accuracy of this release.
