Raintree West delivers additional gold-copper resource to Whistler
Last updated 5/22/2016 at Noon
Brazil Resources Inc. May 17 reported an inaugural mineral resource estimate for the Raintree West deposit at its Whistler copper-gold project, located about 95 miles (150 kilometers) northwest of Anchorage, Alaska.
Located 1,500 meters east of the Whistler deposit, Raintree West is one of several porphyry centers identified on the district-scale Raintree property.
The Raintree West deposit has been subdivided into two zones: A, a block-cave zone that extends from a depth of 100 meters; and B, which runs to a depth of 250 meters and is considered an open-pit zone.
Using a gold-equivalent cut-off grade of 0.6 grams per metric ton, Zone A contains 51.76 million metric tons of inferred resource averaging 0.68 g/t (1.13 million ounces) gold; 3.74 g/t (6.22 oz.) silver; 0.1 percent (114.13 million pounds) copper.
At a gold-equivalent cut-off grade of 0.3 g/t, Zone B contains 31.68 million metric tons of inferred resource averaging 0.4 g/t (409,000 oz.) gold; 5.39 g/t (5.49 million oz.) silver; and 0.06 percent (41.91 million lbs.) copper.
When you calculate the value of the copper and silver, this comes to 2 million gold-equivalent-oz. of inferred resources in the two zones at Raintree West.
This adds to the 2.25 million gold-equivalent-oz. in the indicated category and 3.25 million gold-equivalent-oz. inferred identified at the Whistler deposit; plus 444,000 gold-equivalent-oz. in the indicated category and 1.13 million gold-equivalent-oz. inferred identified at Island Mountain, another deposit located on the expansive Whistler property about 14 miles to the south.
"We are pleased to report this maiden NI 43-101 resource estimate for the Raintree West deposit, which builds on the multimillion-ounce gold resource reported over the last year on the Whistler Project," said Brazil Resources CEO Garnet Dawson.
"In conjunction with advancing our existing project portfolio, the company continues to evaluate resource-stage projects in the Americas for potential acquisition."
