Rare Element Reports - 2007 Drill Program Expands Gold Zone at Bear Lodge Year-end Summary of Sundance Gold Venture
Thursday January 31, 8:30 am ET
Newmont re-started the drill program in October to test extensions of the Carbon target with seven additional holes before year-end. These angle holes intercepted substantial thicknesses of gold mineralization from near surface to depths of 244 meters. All seven holes contain additional low-grade gold mineralization beginning near the surface. The assay results indicate potential for a large-scale oxidized mineralized system and support Newmont's decision to re-start the drill program.
Results for the seven additional holes were provided by Newmont, highlights of which are presented below and details provided in Table 1.
------------------------------------------------------------------------- Hole No. Target From (m) To (m) Interval (m) Gold (g/t) ------------------------------------------------------------------------- SUN-038 Carbon 1.5 86.9 85.4 0.47 ------------------------------------------------------------------------- Includes 48.8 57.9 9.1 1.18 -------------------------------------------------------------------------The scope of the 2007 drill program was restricted to sites that had been previously permitted for exploration drilling, so only three holes were initially planned. Encouraging results warranted the drilling of five additional holes, and a further expansion with another seven drilled, for a total of 15 holes for the year in the permitted area. The original 2007 drilling was designed to gather geological information on the gold mineralization and test concepts and new areas; additional drilling expanded the gold mineralized zones.
A systematic program of drill testing for grade and tonnage of a potentially large gold system is expected to proceed once a new exploration permit is in place allowing much greater flexibility for drill-hole locations than is currently available. Newmont's permitting efforts are progressing in order to allow an expanded drill program on up to 200 acres. Permit approval could occur later in 2008.
Summary of Sundance Gold Venture: Newmont North America Exploration Limited, a subsidiary of Newmont Mining Corporation, is earning an interest in the Company's Bear Lodge property (excluding REEs and uranium) in northeastern Wyoming. Advantages provided to Rare Element Resources by the Sundance gold-focused venture include:
- No expense or substantial effort required by Company personnel; - Full financing for the first five years; - Project management and technical expertise provided by Newmont; and - Added credibility of working with a major gold company.
Rare Element Resources believes that the venture with Newmont will be the best way to maximize the potential of the Bear Lodge gold exploration, while allowing Rare Element Resources to continue evaluating the potential of its rare-earth-element deposits. Adjacent to some of the gold targets are extensive high-grade rare-earth-element (REE) occurrences in carbonatite dikes within the same complex.A revival and recent substantial advancement in the understanding of the alkaline-igneous gold exploration model (in particular at Cripple Creek, Colorado), coupled with the strong gold market, have renewed and intensified gold exploration interest in the Bear Lodge property. The property exposes significant gold occurrences in a large, strongly altered alkaline-igneous complex and these features attracted the attention of several major companies over the years.
The Sundance gold exploration venture at the Company's Bear Lodge property is managed by Newmont. Upon signing of the definitive venture agreement in mid-year 2006, Newmont was conducting geologic mapping, geophysical surveys, soil and rock-chip geochemical surveys, and trenching. The focus of the initial exploration was on the Taylor and Carbonprospects, where historical work had identified gold mineralization. Newmont's work confirms areas of anomalous gold, arsenic, antimony and tellurium on a number of prospects, including all three targets mentioned above, which are coincident with widespread potassic alteration in rocks of the alkaline-intrusive complex. Rock samples from Taylor, where visible gold has been identified in outcrop, consistently returned the highest gold values assaying up to ten grams of gold per tonne. These studies indicate potential for the definition of near-surface gold deposits, as well as potential for deeper higher-grade gold occurrences. Results from the 26 holes drilled by the Sundance gold venture at the Carbon and Taylor targets during 2006 and 2007 indicate thick intercepts of near-surface gold mineralization, with some of the better results including:
- 47.3 m of 0.56 g/t Au (includes 9.1 m of 1.17 g/t) plus 6.1 m of 1.01 g/t Au - Carbon - 38.1 m of 0.40 g/t Au plus 57.9 m of 0.53 g/t Au (includes 12.2 m of 1.09 g/t) - Carbon - 18.3 m of 0.55 g/t Au - Taylor - 111.3 m of 0.40 g/t Au - Taylor - 126.5 m of 0.44 g/t Au (includes 19.8 m of 1.04 g/t) - Taylor - 189.0 m of 0.42 g/t Au (includes 62.5 m of 0.66 g/t) - Taylor - 57.9 m of 0.41 g/t Au (includes 4.6 m of 1.57 g/t) - Carbon - 41.2 m of 0.49 g/t Au - Taylor - 155.5 m of 0.66 g/t Au (includes 36.6 m of 1.35 g/t) - Carbon - 45.7 m of 0.66 g/t Au (includes 13.7 m of 1.33 g/t) - Carbon - 85.4 m of 0.47 g/t Au (includes 9.1 m of 1.18 g/t) - CarbonThe 26 exploration holes drilled by the Sundance gold venture to date all contain gold mineralization and are concentrated on the Carbon and Taylor targets. These two targets are approximately one kilometer apart, and each is approximately two kilometers west of the Smith target area (formerly called the East and West Breccias), which is reported to contain a small historical gold resource.
Exploration work planned for 2008 is designed to build on the successful 2006-07 trenching and drilling program. Work will include, in addition to drilling, detailed geological, geochemical and geophysical studies and completion of the exploration permitting efforts. The gold exploration joint-venture agreement calls for Newmont expenditures to total US$1.2 million prior to June 2008. Newmont has met initial requirements by expending over US$1 million by year-end2007.
Comparison to Cripple Creek: The Bear Lodge district is composed of the upper levels of a mineralized alkaline-igneous complex, which is interpreted to be very similar to the more deeply eroded Cripple Creek alkaline-igneous complex in Colorado. For reference, the Cripple Creek mining district hosts a deposit that has produced more than 23 million ounces of gold since its discovery in 1878. Gold production plus resources for the Cripple Creek district total more than 30 million ounces. Gold occurs primarily in narrow vein sets over a vertical range in excess of 1,000 meters; and economically important gold mineralization also is present near surface in hydrothermal breccias as low-grade, bulk-tonnage deposits that are currently being mined.
Exploration results generated by the Sundance venture highlight the similarities between Cripple Creek and Rare Element Resources' property. The Bear Lodge geology, alteration types, gold grades, and aerial extent of the mineralization continue to fit the Cripple Creek model and are comparable to those of the deposit presently being mined at the profitable, large open-pit Cripple Creek & Victor (CC&V) gold mine in Colorado. For example, drilling at Bear Lodge returned gold values over long intervals that are reported above, and CC&V mine statistics with similar grades and thicknesses were reported in a Company news release of April 17, 2007. For more detailed Sundance results, refer to Company news releases of December 14, 2006 and January 18, 2007 and October 2, 2007.
Some key aspects of the gold exploration model and the similarities between Bear Lodge and Cripple Creek are as follows:
- At Bear Lodge and Cripple Creek, many surface rock-chip samples, collected by a variety of major companies over the last 30 years, carry gold values in excess of one g/t. Historically, the highest grade of these samples assayed over fourteen g/t gold at Bear Lodge. - Broad areas have strong (greater than or equal to 100 parts per billion (ppb) gold) and moderate (50 to 99 ppb gold) gold anomalies in rock- chip and soil samples (100 ppb (equal sign) 0.1 ppm (equal sign) 0.1 g/t). - Gold mineralization is structurally controlled and closely associated with widespread strong potassium feldspar-pyrite (+/- carbonate) metasomatic alteration. - Veinlets and wall rocks contain disseminated rare-earth-element minerals, and apatite crystals have rims enriched in rare-earth elements. - Other anomalous elements that characterize mineralization in the complexes include potassium, tellurium, arsenic, antimony, molybdenum, barium and strontium. - The Bear Lodge alkaline-igneous rocks, which are dominated by phonolitic and trachytic sills, dikes, and plugs (as well as numerous related late-stage intrusions and intrusive breccia bodies), could represent the upper levels of an alkaline-igneous system similar to that exposed at Cripple Creek.The Bear Lodge property has a well- documented, hydrothermally altered and mineralized system with rock types, minerals and structures that match major features of the alkaline-igneous gold exploration model as it is expressed at Cripple Creek. Past exploration efforts paid little attention to the Bear Lodge potential for deeper-seated, high-grade gold deposits targeted by the Cripple Creek model; and near-surface low-grade, bulk-tonnage gold mineralization has become more economically significant with the increase in gold price. We now have an excellent gold exploration venture, which is based on this model and operated by Newmont, one of the best gold exploration teams in the mining industry. The Sundance partners look forward to the 2008 exploration program to confirm and expand on the earlier results.
