WHITE ROCK

White Rock

Project Overview

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 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.

What Does White Rock Offer?

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.

Historic Exploration Drilling

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:

  • WR-3 - Starting at 42m, 39m at 0.48 g/t plus 19m at 1 g/t and 3m at 5.7 g/t
  • RR-41 - Starting at 2m, 73m at 0.55 g/t 
  • RR-8 - Starting at 3m, 77m at 0.41 g/t
  • RR-38 - Starting at surface, 84m at 0.35 g/t plus 23m at 0.38 g/t
  • RR-47 - Starting at 25m, 32m at 0.655 g/t
  • RR-45 - Starting at 4m, 48m at 0.49 g/t 
  • Many more not shown

Property Geology

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.

2021 Completed Drill Program

Provenance has completed an initial drill program on 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 then progressed southeastward toward the strongest surface mineralization.  Challenging drilling conditions that shouldn’t present difficulties going forward 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 was 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.  

Provenance believes the geology of the White Rock mineral system has similarities to the geology could have similarities to the nearby operating Black Pine open-pit 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.   The focus of the initial drill program was 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.

2022 Technical Report

Click here to view the White Rock Technical Report

An initial NI 43-101 technical report has been completed on the White Rock Gold Property. The purpose of this report was to form a baseline for the Property and will be updated further in 2023 following a second drill program planned that is fully permitted. The planned drill program is being designed to expand upon significant zones of gold mineralization confirmed during the 2021 drill program. Highlights include:

The following points are highlights of the technical report:

  • The Property is very large with gold mineralization being found over three-square kilometers that hosts gold in feeder structures, silicified limestones and silicified sandstones and shales.
  • The Property has on the surface to near surface gold mineralization over significant widths and thickness associated with a > 3.5 km2 alteration system, and affinities of both sediment-hosted low-sulfidation epithermal and Carlin styles of mineralization.
  • Significant exploration potential is found on undrilled or under-drilled portions of the property in 2021; including the newly recognized feeder structure on Central Ridge.
  • There is a strong correlation between the 2021 and historic assay values from twinned holes on the property, indicating the historic data is valid and can be relied upon for future exploration and evaluation.
  • The authors of the technical report recommend that the Property be advanced with a large drilling program, metallurgical test work and a thorough database audit in preparation for resource modeling.
