Location and Land Position
Harvest Gold’s Rosebud Gold Mine Project consists of 54 claims (approximately 1,067 acres) centered on and surrounding the former Rosebud Mine. The property package is in northwest Nevada approximately five miles to the south of the Hycroft Mine which has produced more than 1,000,000 oz Au, 2,000,000 oz Ag and has recently resumed production. Rosebud is part of a large, robust, low-sulfidation hydrothermal system that extends throughout most of the Kamma Mountains.
Past Production
Rosebud was mined by a Hecla-Newmont joint venture between 1997 and 2000 producing 396,842 ounces gold (avg. grade 0.4164 oz Au/t) and 2,309,876 ounces silver (avg. grade 2.42 oz Ag/t) from high grade ores. The mine was one of the highest-grade modern gold producers in Nevada (grades up to 46.2 oz Au/t).

Resources
In 1995, prior to the commencement of mining, Hecla calculated a resource of 13,452,000 tons grading 0.066 oz Au/t, 0.797 oz Ag/t for 891,460 oz Au and 10.7 million oz Ag. In late 2000, following closure of the Rosebud Mine, at a time when gold prices had fallen to US$252/oz Au, Hecla reported an historical remaining Measured and Indicated Global Resource of 6,816,021 tons grading 0.036 oz Au/t and 0.31 oz Ag/t at a 0.01 oz Au/t cut-off, containing 242,857 gold ounces and 2,129,750 silver ounces (Hecla Mining Company, 2000). These historical estimates were made prior to the implementation of NI 43-101, may not comply with current CIM standards, and are presented for purposes of historical reference only. The Company is not treating the estimates as a National Instrument 43-101 defined resource, and the historical estimates should not be relied upon. In-place, high-grade gold intercepts are present in several areas peripheral to the mine workings.
Reinterpretation, High-Grade, Bulk Tonnage, Drill Targets
Harvest has reinterpreted the geology at Rosebud and prioritized 11 high quality targets on the property. Because of this new understanding of the geology, particularly the structural controls on mineralization, the Company believes that there is very good potential to discover additional high grade zones within and adjacent to the bulk tonnage envelope, and to expand the size of this envelope.
A NI 43-101 Technical Report was completed in September 2008 (click here to view). The report’s author recommends an aggressive two-phase drill program to explore for high-grade zones in the most prospective targets and to expand the bulk tonnage mineral envelopes.
The first phase of this drilling has been completed and results are discussed below.

Historical Drill Intercepts
Many high-grade historical drill intercepts are present in targets peripheral to the underground mine workings; selected results are shown below.
Drill holes were completed by Lac Minerals (RL series) between 1989 and 1992, Hecla (WW-1 and 96-356) in 1994 and 1996, and a Hecla/Newmont joint venture (RS and SLD series) between 1997 and 2000. Diamond drilling core holes are denoted by a “c”; except for WW-1, which was a water well completed by rotary drilling, all others are reverse circulation drill holes. True widths of these intercepts are unknown.
