MacMillan Gold Reports Copper And Silver Values From The Mahone Target At The Tetasiari Project
TORONTO, ONTARIO--(CCNMatthews - Jan. 13, 2006) - George A. Brown, President & CEO of MacMillan Gold Corp. (TSX VENTURE:MMG) is pleased to announce positive results from the October 2005 sampling program at the Mahone Copper-Silver Target. The Mahone Target is part of the expansion claims of the Tetasiari Joint Venture Project in northern Sinaloa State in Mexico which was terminated on November 14, 2005 by Consolidated Spire Ltd. (TSX VENTURE:CZS). The Mahone property acquisition was funded 100% by Spire and these work programs were completed prior to termination by Spire. MacMillan Gold now holds a 100% interest in the entire Tetasiari Project consisting of over 16,000 hectares near Pan American's Alamo Dorado deposit. The Alamo Dorado and other significant precious metal prospects in the district including the Tetasiari are located near the margins of the Sinaloa granitoid batholith. The Tetasiari project covers selected target areas along approximately 45 km of strike, including numerous precious metal prospects and geochemical anomalies in an area with a long history of artisanal vein and alluvial gold mining but very little modern exploration. The Tetasiari project is being developed to explore for large tonnage, bulk mineable precious metals deposits.
The Mahone Copper Silver Target is located on the 100 hectare Phi claim. The prospect consists of an old copper working, which was apparently exploited as recently as the 1980's. The host rock is altered and brecciated andesitic volcanics. The mineralized zone consists of two parallel southeast striking, northeast dipping brittle to brittle-ductile fault zones. The fault zones are separated by a 5.65 metre true width of silicified, and mineralized material. Seven channel samples were collected across the zone, which is mineralized with malachite and azurite, as well as copper oxide minerals. The assay results are as follows:
Channel Samples g Ag/t % Copper ------ ---------0.2 m. 60.0 5.0400.4 m. 182.0 0.8572.0 m. 75.4 1.4500.75 m. 27.1 0.6731.4 m. 37.1 0.5691.5 m. 7.6 0.2711.0 m. 52.0 1.120------ ------- ------7.25 m. estimated true width Weighted Average: 51.2 g 0.976% Ag/t Cu
Although the samples were collected from available sampling surfaces staggered across the zone, they reflect a continuous sample sequence across the mineralization. Alteration and brecciation of the host rock is present on both sides of the mineralization reported above indicating the potential to expand the zone in both directions.
A third fault is located 25 m. southeast of the 2 faults reported above. This fault zone trends slightly oblique to the two main faults. The channel sample from this zone reported 31.4 g Ag/t and 1.31% Cu over a true width of 1.0 m. The area between the 2 fault systems consists of brecciated andesitic volcanics. This indicates the potential for the overall width of the zone to exceed 12.0 m.
Mineralized float material has been observed for about 100 m. along strike to the southeast, although no extensions of the zone have been observed in outcrop. In order to further evaluate this zone, 130 soil samples have been collected from a grid covering the target area. The assays from these soil samples have not yet been received.
