Spanish Mountain Gold
Projects Overview Newfoundland & Labrador British Columbia
Detailed GeologyKnown placer workings in the area include the Cedar Creek Placers, the McKeown Placers, and the historic Bullion Pit - one of the largest placer gold mines in the world, measuring 1500 m by 450 m by 125 m (4920' by 1476' by 410'). Spanish Mountain has been proposed as the possible source of these gold-rich gravels (Minfile 093A 043).
Mineralization is hosted by highly folded and faulted metasedimentary rocks with some interstratified volcanics of the Nicola Group. The metasedimentary rock consists of slaty to phyllitic, dark grey to black shale and siltstone, grey limestone and some banded tuff, volcanic breccia and pillow lavas higher in the stratigraphy.
Spanish Mountain DevelopmentsWork by Spanish Mountain Gold Ltd. (SMGL, formerly Skygold Resources) has been successful in outlining large areas of low-grade gold mineralization close to surface, with bulk mineable potential. Gold-bearing zones are stratigraphically controlled, trend NW-SE, and extend over 1.44 sq.km (over 0.56 sq.mi.), open in all directions. Spanish Mountain was recently interpreted as a Sediment Hosted Vein Deposit (see SHV Deposits section).
This section is a summary of published findings, including Geochemistry, Drilling, Metallurgy and Geophysics, as contained in the websites and sedar filings of SMGL/Skygold. Please see www.spanishmountaingold.com for current information.
Gold mineralization on Spanish Mountain is described as of two types:
Freeport's 2007 reconnaissance sampling survey revealed significant gold anomalies suggesting continuity of the mineralized zone eastward. Soil and rock samples collected over a geophysical 'resistivity low' reach over 400 ppb in soil and up to 0.13 g/t in weathered pyritic argillite and greywacke surface rocks -- the same rock types as seen at SMGL/Skygold's mineralized horizon.
GeophysicsIn 2006, a DIGHEM electromagnetic/resistivity/magnetic survey was flown over Spanish Mountain. Geophysical resistivity lows reportedly correspond with broad zones of argillite favourable for sediment hosted gold; mineralization is associated with a contact between argillites and greywackes, with higher grade gold in greywacke host rock. The low resistivity anomalies extend onto Freeport's claims. Trenching over geophysical anomalies has successfully located new gold-bearing horizons.
Drilling & ResultsNotable intersections reported by Skygold include 29.07 g/t gold (.847 oz/ton) over 10 metres (32.8') and 7.99 g/t gold (.233 oz/ton) over 19 metres (62.3'). Lower grade intercepts include 1.81g/t gold over 94.5 metres, 1.34g/t gold over 116 metres and 1.30g/t gold over 86.9 metres. A bulk sample of 2,100 tonnes taken in 2000 averaged 3.02 grams Au/ton.
Skygold noted, "...the zone may be getting wider to the east" (2007.09.10). Reverse circulation holes have been drilled within 54 metres (177 feet) of Freeport's west property boundary. Published results from the adjacent PESO claims include:
Conclusion & RecommendationsIn summary, anomalous gold in samples from areas of low resistivity on Freeport's claims suggests continuity of SMGL/Skygold's gold-bearing Main Zone to the west.
A multi-stage program of sampling, trenching and drilling to verify extension of the mineralized zone over Freeport's property is recommended.
