A section of zinc rich mineralization has been encountered at Colony Pacific Explorations’ Blue Moon property in California. Westmin Resources has already spent $2.7 million(US) on the property and more than one third of its proposed 1987 budget of $1.25 million.
The program is designed to improve and expand ore reserves and the latest results suggest an up-dip extension of the orebody in two zones. Hole No B47 intersected a true thickness of 9.1 ft grading 0.052 oz gold, 2.99 oz silver, 0.54% copper, 0.73% lead and 12.37% zinc in the West zone. A deeper intercept, this one in the Main zone, returned 18.6 ft grading 0.008 oz gold, 0.78 oz silver, 2.47% copper and 16.64% zinc.
The hole was drilled from surface to test an area about 200 ft above B43 which encountered grades of 34% and 20.4% zinc over true thicknesses of 8.6 ft and 9.0 ft respectively. There were also significant precious and base metal credits in that hole.
The style of the recent mineralization intersected in the Main zone suggests the area is near the centre of the mineralizing system, the companies point out. The mineralized zone has been noted in another hole (B48) about 250 ft above and 50 ft south of hole B47. Visual examination of the core has revealed significant faulting and semi- massive pyrite in the West zone. One 2.2-ft intersection in the Main zone included massive sulphide/ sulphate mineralization with significant tetrahedrite and sphalerite bounded on each side by less massive mineralization.
Westmin can earn a 50% interest in the property by spending $5 million(US) by Dec 31, 1988. Colony Pacific’s interest is carried until then.
