Provenance’s White Rock property in the northeastern corner of Elko County, Nevada hosts a large gold system within its 258 claims covering 5,160 acres. The gold system extends across an open-ended area of at least 3.2 Km by 1.6 Km. The gold system is hosted in Permian sedimentary formations and is both structurally and stratigraphically controlled. The structural controls include a north-trending fault system and a faulted complex anticline. The anticlinal structure is believed to be developed on the upper plate of an underlying thrust sheet complex. Scattered widely spaced historic drilling of parts of the property with distances between holes up to 290 meters apart confirmed the extensive mineral system. The drill holes intersected thick intervals of open-pit grade gold mineralization up to 5.7 g/t gold. Provenance believes the geology of the White Rock mineral system has similarities to the geology of the nearby Black Pine gold system in southern Idaho. At Black Pine, the gold system is hosted in a complex of thrust faults. A similar thrust complex underlies the White Rock mineralization, and the thrust complex will be a future exploration target.
All past drilling was widely spaced with distances between holes ranging from 200 feet (66m) to about 900 feet (290m) and was open ended on trend. Current interpretation leads the Company to believe the property contains a large shallow gold system. The bulk grade of the mineral resource is comparable to currently operating large open-pit gold mines.
A review of 65 historic drill holes found 191 intervals that assayed between 0.01 opt gold (0.34 g/t) to 0.166 opt gold (5.7 g/t) over intervals from 10 to 95 feet. These holes were widely spaced with distances between holes up to 290 meters apart and over a mineralized area of approximately four-square kilometers. Significant historic intercepts included:
The White Rock property consists of 258 claims covering 5,160 acres. Provenance has an Option to Purchase 100% for US$250,000 over 4 year option term. Advanced royalty payments set annually at US$25,000 after purchase completed with a 2% NSR royalty on production for the Vendor.
The property is located in a NW trending wrench fault system and is hosted in Permian cherts, limey cherts, and limey siltstones. The property features an epithermal system with fracture controlled gold deposition. Sedimentary host rocks are silicified (jasperoids), limonitic and brecciated, with gold mineralization introduced during early structural development in stockworks in brittle zones. The nearest gold mine is Liberty Gold's Black Pine Mine which Provenance believes is in a similar geological setting.
15 holes drilled with 8 ore holes, WR3 has highest grade intercept found (0.166 opt Au), open in all directions.
12 holes drilled, significant gold found, step outs required
Structural intersection, numerous ore holes, step outs required
6 holes drilled, drilled under structure and missed, major soil anomaly
Provenance is currently drilling the property to confirm the historic drilling and Provenance’s new gold system model. Although the gold system extends northwestward through White Rock Mountain and well beyond, Provenance’s initial program started on the southeastern margin of the mountain because of easy access and a good historic data base. The drilling is progressing southeastward toward the strongest surface mineralization. Challenging drilling conditions that won’t present difficulties for a mine have resulted in many holes having to be terminated before cutting through their targets, although most have reached the upper levels of the gold system. The completed holes and partially completed holes together with historic information and detailed structural modeling substantiate Provenance’s gold mineralization model and the large size and thickness of the gold system. Two of Provenance’s holes that successfully penetrated the gold zone in the company’s initial northern drilling target area provide confidence the zone is thick and continuous.
Hole WR-15 was drilled vertically to test disseminated gold mineralization in the sedimentary rocks that host the system. Starting with 2.35 g/t gold over 1.5 meters, a strong interval of 29 meters of 0.636 g/t gold was followed closely by another 53 meters of 0.197 g/t gold. Both intervals each contained 7.6 meters of 1.45 g/t and 0.427 g/t gold. The anomalous gold mineralized zone had a cumulate thickness of 100 meters (328 feet).
WR-16 intersected a 55-meter (180 feet) interval that averaged 0.618 g/t gold starting with 1.5 meters of 3.55 g/t at 29 meters and ending with a 6-meter interval that averaged 2.3 g/t. The 55-meter-thick zone also contained 7 assay intervals over 1 g/t gold. It was stopped at 100 meters (328 feet) due to drilling conditions. The hole remains open to mineralization to depth. Based on historical data, Provenance believes another mineralized zone occurs below the one that was intersected by hole WR-16.
Hole 23 was an 800-meter step-out to the southeast, but still northwest of the strongest surface mineralization. It was drilled to a depth of 146 meters (480 feet) with strong mineralization beginning at the surface and continuing to 117 meters (384 feet). The hole intersected 85 meters averaging 0.369 g/t gold to a depth of 94 meters. Within that hole were higher grade intervals such as 0.778 g/t gold from 38 meters to 46 meters.
The focus of the initial drill program is to confirm and expand on historic drilling that intersected thick intervals of continuous gold mineralization within the 3.2 Km by 1.6Km core area of upper plate gold mineralization. Simultaneously, Provenance is mapping and sampling additional areas of adjacent and nearby gold mineralization.
