The White Point mineral resource has an effective date of June 13, 2022 and based on the drilling results as of 31.12.2021. The inferred resource is in addition to the measured and indicated resource. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Numbers have been rounded, which may lead to some numbers not adding up exactly. The resource estimate reflects gross metal content that is not adjusted for metallurgical recoveries.
Highlights include:
- 0.82 g/t gold equivalent over 36.6 meters within hole WP-21-005,
- 1.40 g/t gold equivalent over 15.3 meters within hole WP-21-006,
- 0.70 g/t gold equivalent over 13.7 meters within hole WP-21-002,
- 0.56 g/t gold equivalent over 19.9 meters within hole WP-21-003.
Description:
White Point is located just 400 meters west of the Grey Eagle resource, on the Nevada side of the Gold Springs project.
This target is characterized by an outcropping, gold bearing, sheeted vein zone consisting of individual veins 0.5 to 5 meters in thickness
White Point, along with Midnight, is unique in the Gold Springs project area in that mineralization is controlled by a wide zone of veins formed in a large structural setting. Both targets have historic mines with very high-grade veins that were exploited in the early 1900s.
The vein zone at White Point is over 200 meters wide with the spacing between veins ranges from a few centimeters to several meters. This high density of veins creates a large tonnage bulk mineable target. The entire zone can be followed along strike for 400 meters with projected extensions covered by younger post-mineral rocks. These same younger rocks cover much of the Grey Eagle deposit which may be connected to White Point at depth.
Historical:
The White Point Mine was located along an extensive stockwork structure trending in a northerly direction and was exploited in the early 1900s. Two adits and a shaft were developed on the sheeted gold bearing vein zone +200 meters wide. The mine is credited with at least one ore shipment in 1935 of 37.2 tons grading 17.75 g/t of gold. One GRC sample of the vein assayed 18 g/t gold.
Gold equivalent based on US$1,800/oz gold, US$25/oz silver and 50% for silver recovery. True thickness is estimated to be 70-100% of reported length.
Drilling results:
A total of 5 holes were drilled at White Point in 2011 but all were lost before reaching the main target zone due to difficult drilling conditions. GRC has now constructed drill pads at locations which will allow for an efficient first pass test of this exciting target. Plans are to drill White Point in August of 2021 with the first assay results expected in September-October 2021. The significant drill results from 2011 were as follows:

Geology:
Historical mining activities at White Point focused on a 200 meters wide zone of sheeted veins within an andesite host rock which can be traced for 400 meters on surface prior to being obscured by post-mineral cover. White Point displays complex structures which not only control the extensive sheeted vein system but have down-dropped portions of the system where it is covered by the post-mineral tuff unit. In these down dropped areas more of the system should be preserved making them attractive drill targets. This cover occurs to the south and east of the White Point where the potential extension of the sheeted vein zone is separated from the Grey Eagle resource by one of the tuff-filled, down-dropped fault blocks. This is also the area where a major northeast trending fault system is projected to intersect the caldera margin which hosts the Grey Eagle resource.
- System Type: Low sulphidation epithermal system comprised of a sheeted quartz-calcite vein zone, surrounded by stockwork veining and brecciation.
- Strike-Length: The White Point target has a width of 200 meters and a strike-length of 400 meters before being obscured by post-mineral cover.
- Structural Geology: The structural setting at White Point is dominated by the intersection of a northeast-trending fault systems that controls the exposed vein system and is reflected in the orientation of the ZTEM resistivity anomaly with the caldera margin that hosts the Grey Eagle resource (see maps below). This projected intersection is under post-mineral tuffs.
Geophysics:
The White Point target is situated along a resistivity high anomaly which is also associated with the Grey Eagle resource, as identified in the airborne ZTEM geophysical survey (see maps below). This ZTEM feature can be traced for +2 kilometers to the northwest into areas predominantly covered by post-mineral colluvium (gravels). It highlights a strong resistivity response like that found in all of the current resource areas.
Geochemistry:
Mineralized zones consist of 0.5 to 5 meters wide quartz-calcite veins, strongly silicified breccias and extensive stockwork veining. Several historical mines exploited both individual veins and sheeted vein zones. GRC sampling has generated grades of up to 8.4 g/t gold from these historical workings. The potential for significant bulk gold mineralization is highlighted by some of GRC pas sampling where surface channel samples returned the following values:

Recent geologic mapping with associated surface sampling by GRC has further defined the White Point target which is now drill ready. The recent sampling produced the following results with gold grades greater than 0.25 g/t Au (cutoff grade of the existing resources at Gold Springs). Previous sample results of the Company can be found below as well.
