Warrior Project – High Grade Epithermal Gold
The Warrior Project is accessed directly via gravel state route 89 (Poleline Road) being some 25km southeast of State Hwy 361. The nearest town is Gabbs, located 32km to the northwest, with the regional centre of Tonopah being 80km NW of the Warrior Project also accessed via state route 89.
Sierra Nevada’s Warrior Project is a large historic mining centre contained within a substantial alteration system that is prospective for high grade vein and disseminated Au-Ag epithermal, skarn breccia and carlin style deposits. The Warrior Project exhibits many similarities to and is located just 15km’s from the world class Paradise Peak high sulphidation epithermal mine (2Moz Au & 40Moz Ag). The Warrior Project consists of 260, 20 acre claims and covers an area of 21km2. The Warrior Project hosts a large mining camp with four main historic mining centres each of which exploited high grade epithermal mineralisation. Those mines Warrior, Hillside, Cute Maid and Lou Mines are situated along a distinct northeast alignment. The largest of the historic mining centres is Warrior where historical records from the 1920’s reveal bonanza grade veins were the focus of mining.
Warrior Project is located within the Walker Lane Trend of southern Nevada. The Walker Lane Trend is a world class mineral province that host numerous world class mineral deposits including the giant Round Mountain deposit (20Moz Au), Comstock (8.5Moz Au, 200Moz Ag), Yerington Porphyry (4Mt Cu) and Candelaria (230Moz Ag). The Walker Lane Trend has recorded production and reserves of 50Moz Au, 700Moz Ag and 4Mt of Cu.
The Warrior Mine was discovered via a small outcropping Gossan in 1904. Mining at the Warrior Mine commenced in 1915 by early prospectors before acquisition by Olympic Mines Co. in 1921. Mining activities focused on near-surface NW orientated quartz veins which produced Au, Ag and Hg. Ore from these mines averaged approximately 31g/t Au and production ceased prior to the 1940’s. Records of mapping and sampling during this early mining phase has been used by Sierra Nevada to create a 3D model of the historic workings, veins, and structure at the Warrior Mine. The historic sampling demonstrates the very high-grade nature of the veins mined at the Warrior Mine.
Placid Oil and AMOCO acquired the exploration rights to the Warrior Project in the early 1980’s and completed 25 drillholes (2,680m) exploring for shallow deposits based on the Paradise Peak model. Better results reported from these holes include 3.05m @ 1.53g/t Au from Warrior NW (WAR 10), 1.52m @ 1.75g/t Au from Hillside (WAR 9-85), 3.05m @ 2.62g/t Au from Cute Maid (WAR 4-85), 1.52m @ 2.90g/t Au from Lou Mine Area (WAR 1-85). No further exploration has been undertaken within the project until Sierra Nevada took control of the project in 2014.
Since 2014 Sierra Nevada has explored the project in detail and acquired several datasets that define large scale and fertile hydrothermal systems synonymous with epithermal, skarn related and carlin style deposits. The company has conducted successful RC drilling, detailed mineral system mapping and targeting which has resulted in a suite of advanced high priority targets ready for further exploration and drill testing based on;
- GEOCHEMISTRY – Large coherent anomalies synonymous with epithermal deposits.
- SPECTRAL – Defined high and low sulphidation epithermal and skarn signatures.
- MAGNETICS – Large scale structures, large alteration zones and concealed intrusions defined – skarn targets identified.
- CSAMT – Extensive survey has defined zones of alteration (silicification) marking major fluid conduits defining immediate drill targets. Sierra Nevada RC drill tested one such target (2015) returning approximately 100m @ 0.3g/t Au from a silicified tuff unit 500m to the SW of the high-grade Warrior mine.
The mineral systems defined within, and the location of, the Warrior Project within a highly endowed and prospective district supports the implementation of an aggressive drilling-based program that has the potential to rapidly deliver a discovery. Sierra Nevada has developed a suite of advanced drill ready targets with the potential to make step change discoveries in the near term. For example, there has been no previous drilling targeting the immediate Warrior Mine which presents an immediate drill target for Sierra Nevada.
