Bravada Projects

SF property

The SF Property is located in Eureka County on the Battle Mountain Gold Trend, directly east of the Cortez Mining District, The property consists of 66 unpatented mining claims.   Bravada holds an option to acquire a 100% interest in the claims.  Should production occur from the property, a 1% NSR would be paid to the owner, one-half of which (0.5%) could be bought for US$3,000,000.

Weak gold mineralization exposed at the surface on the SF Property occurs in Paleozoic sedimentary rocks, and the characteristics of the mineralization are similar to the distal portions of numerous Carlin-type gold deposits.  Three samples collected from silicified siltstone and chert float/subcrop on the east side of the SF group contain from 0.06g/t to 0.1g/t Au.  Another sample of limestone float from the center of the property contains 0.057g/t Au.

Drilling on the HC claims by J-Pacific Gold Inc., within 200m of the eastern border of the SF Property,  intersected narrow zones of +0.3 g/t Au associated with highly altered Tertiary(?) dikes in a down-dropped block of younger Paleozoic sediments than are exposed on the SF property.  The mineralization in this drill hole may be distal leakage from the target that is recommended for testing on the SF Property.

The alteration and mineralization at the surface and in the drill hole are believed to be controlled by a northwest-trending, horst-bounding fault that is covered by gravel.  The rocks exposed at the surface of the property are the Horse Canyon and Wenban Formations, important host rocks in the Cortez Mining District.  The most favorable portions of these formations lie at depth beneath the areas of anomalous geochemistry and alteration.

Bravada also collected soil samples from lineaments that are interpreted as fault scarps in the pediment between, and to the south of, the exposed Paleozoic-age rocks.  Anomalous gold values of 0.019 to 0.039g/t Au may delineate hidden mineralized structures beneath Quaternary alluvium.  A total of five sites are permitted and bonded for drilling.

Recently published data on Nevada stratigraphy and structure has led to a reinterpretation of stratigraphy and structure at SF, greatly upgrading an untested target as shown in the cross section below. The SF property is east of Barrick’s Goldrush deposit (Carlin type) and southeast of the past-producing Buckhorn mine (low-sulfidation type). Goldrush is on the western margin of the Nevada Rift and SF is on the eastern margin. Unit #5 of the Wenban formation is a major host rock in the region and should underlie the upper Wenban and Horse Canyon formations, which are exposed at surface. The thrust interpretation fits the map patterns better than the original interpretation, and the new interpretation makes a much stronger gold target. Exposure is very poor; however, diagnostic fossils have been identified that mark the transition between the Wenban and Horse Canyon formations.
