East Walker consists of 50 new claims (approximately 405 hectares) staked on open ground on BLM-administered Federal land located in Lyon County, Nevada in the Walker Lane Gold trend.
A proposed Phase 1 exploration program, subject to funding consists of:
- Completing acquisition of prospective ground;
- Completing compilation of historic assays and limited drill data;
- Integrating historic data with detailed geologic mapping;
- Sampling potential mineralized structures for assay; and
- Defining initial geophysical surveys.
President Joe Kizis commented, “East Walker is in one of the most active exploration areas in Nevada and is a great example of the type of property that Bravada targets for acquisition and exploration, being a large mineralized system with potentially high grades of gold and silver where major new deposits are being discovered.”
The Company’s newest project has geologic features comparable to large, high-grade low-sulfidation -type gold deposits like AngloGold Ashanti’s discovery at Silicon/Merlin, which is also located within Nevada’s prolific Walker Lane Gold trend. Bravada has assembled a large amount of historic data for the East Walker project and surrounding region, which was acquired by staking 50 lode mining claims on open Federal ground.
Historic data includes widely spaced surface rock-chip samples, with many grab samples assaying over 100ppb gold. More importantly, several 1980’s-vintage conventional-rotary drill holes were drilled on a small part of the claim group where they intersected gold assays of 0.4g/t to over 1g/t gold over significant intervals. Investors are cautioned that conventional-rotary holes may include significant contamination from barren material from above mineralized intervals and, conversely, caving from mineralized intervals may contaminate unmineralized areas below. The Company considers this surface and drill data to be historic and cannot be relied upon. However, with this caution in mind and the understanding that the Company cannot fully verify historic sampling methods, it is encouraging that companies that were highly credible during the mid-1980’s reported significant concentrations of gold in deeply eroded portions of the stratigraphy.
Importantly, most of the property is not as deeply eroded as in the canyon where the historic holes were drilled, and reconnaissance-stage geologic mapping in topographically higher areas has identified widespread regions of the upper stratigraphy with preserved paleosurface “hot springs” features, including geyserite, hydrothermal breccia with blocks of sinter, steam-heated alteration, and distal ground-water silica-replacement horizons. Exposed in lower topographic regions below these paleosurface features is intense clay alteration with abundant gypsum, indicative of alteration by a highly acidic hydrothermal fluid generated by boiling at depth where gold may have been deposited. Frequently in these well-studied types of deposits, the surface features are nearly barren of gold, with values typically 100 ppb Au or lower. Major gold deposits typically occur 150 to 200 metres beneath such paleosurface features.
