Overview
The Company has acquired a major land position in one of North America's oldest silver regions, the Ainsworth camp. The mineral titles are owned 100 per cent by Goldcliff. The claim holdings are contiguous and cover an area of approximately 57,517 hectares (142,067 acres). The claim holdings contain old silver producers and a number of strongly anomalous silver, copper, molybdenum, lead, zinc and gold values. The Loki molybdenum showing is located on the claims. Goldcliff's interpretation of the region's geological, geochemical and geophysical data established an exploration model for mega-silver-deposit discoveries in the region. The region has historical silver production of 85 million ounces silver.
Goldcliff's 2007 exploration program will focus on the regions mega-silver-deposits potential rather than on individual silver deposits. In order to focus the 2007 field exploration, the Company has located geological, geochemical and geophysical anomalies for silver and molybdenum investigation.
Goldcliff's silver exploration model focuses on the younger intrusions as the source of the silver mineralization and the older intrusions/sediments as the receiver of the silver mineralization. The traditional silver mined in the district came from shears and veins of high grade silver deposits in intrusive and sedimentary rocks. As such, Goldcliff's silver model targets the lower-grade silver mineralization that is associated with the high grade silver veins. The host rocks are intrusive and/or sedimentary rocks that are associated with structural breaks, stock-works and intrusive-sedimentary contacts. This silver-dissemination model is evidenced on the west side of Kootenay Lake in the Ainsworth District where high grade silver deposits occur along and within the geological model.
The Goldcliff claims in the Ainsworth District cover numerous high-grade silver deposits and several valleys are targeted for airborne and ground exploration. In one valley, eight silver deposits have been recorded with the historical silver production of silver grades ranging from 100 to 300 grams silver per tonne (MinFile Reports). The silver mineralization occurs in deposits that are in intrusive rocks, located to the west of the valley, and sedimentary rocks, located to the east. The silver deposits trend in an east-west direction and extend over a distance of 10 kilometres. The area between these two different silver deposit settings is geologically favourable for new silver deposit discoveries.
For molybdenum on the Ainsworth claims, Goldcliff is particularly interested in the Loki molybdenum occurrence that is located on the east side of Kootenay Lake on the Ainsworth project. In 1980, Duval International Corp. discovered the Loki molybdenum showing. Duval's work identified a kilometre long molybdenum soil geochemical anomaly in a porphyry setting. The rock chip follow-up sampling confirmed the source of the soil anomaly and returned values as high as 1180 ppm molybdenum from outcrop. Goldcliff plans an airborne electromagnetic and magnetic geophysical survey for the Ainsworth project to further enhance its geological silver model and expand on its porphyry molybdenum mineralization potential.
