White Rock Minerals Ltd (ASX:WRM) is set to begin drilling at Last Chance gold prospect within the Red Mountain project in Alaska after receiving further high-grade results from rock chip and soil sampling.
The samples were collected during geological reconnaissance and systematic soil sampling of the highly prospective target within the prolific Tintina gold province.
They have provided the company with high expectations for its initial drilling campaign set to begin by August 1.
There were more than 500 rock chip samples and 2,800 soil samples collected and submitted to the laboratory for analysis.
Results received to date include:
- Up to 77.5 g/t gold in rock chip samples returned from a single quartz vein, potentially representing leakage from deeper, higher grade parts of the system; and
- Peak results of up to 7.1 g/t gold from soil samples.
Systematic soil sampling has defined an extensive footprint of gold anomalism throughout the 6-kilometre strike extent with 138 samples assaying greater than 100 parts per billion gold and a further 38 samples greater than 400ppb.
Last Chance targets
Systematic soil sampling has defined an extensive zone of anomalous gold, arsenic and to lesser extent antimony throughout the core target area, which appear closely associated with hydrothermal silica breccias and associated veins.
White Rock believes these breccias and veins are a high-level expression of a deeper gold system.
The best defined of these are centred on the Sidewinder West and Pickle areas, which will be the focus of initial drilling testing for both shallow mineralisation as well as somewhat deeper feeder structures beneath.
At the Sidewinder West area, a strongly anomalous soil sample cluster includes assay results of 7.1 and 2.2 g/t with each of these high gold soil clusters potential high-priority drill targets.
Gold soil assays results received to date.
Diamond drilling planned
A first phase diamond drilling is scheduled to commence prior to August 1, 2020.
The first priority is to test several immediate targets to assess the potential for shallow economic gold mineralisation associated with the robust hydrothermal silica breccia bodies and associated quartz veining.
Initial drilling will likely provide valuable geologic information with which to further interpret the geometry, orientation and relationship of these important breccias and veins as well as better understand their full extent underneath talus cover.
The drill program will then include a series of deeper holes designed to follow leakage vectors downward to test for potentially high-grade gold mineralisation at depth.
