Midnight

Highlights:

  • Sheeted gold bearing vein zone 200 meters wide tracable for 650 meters.
  • Historic mines exploited in the early 1900s with the deepest shaft in the Gold Springs Project displaying very high-grade veins which have assayed as high as 57.3 g/t Au.
  • Scattered high-grade float material downslope of Midnight ranging up to 22.4 g/t Au.
  • This target has significant potential.

Description:

The Midnight target is located 2,700 meters west of the South Jumbo resource and displays multiple parallel sheeted calcite-quartz veins, breccia and stockwork zones over widths of up to 200 meters and that can be traced for 650 meters along strike before being obscured by post mineral gravels in all directions.Several historic workings are located on high-grade veins at Midinght including the deepest shaft within the Gold Springs project. The large dump indicates there was extensive roduction from the Midnight mine, but no historical records have been found.

Drilling Results:

The first drilling at Midnight is expected to start in September 2021 and will target areas of historic mining and areas producing high-grade gold samples.

Resource:

None at this time.

Geology:

Mineralization consists of multiple parallel zones hosting sheeted, calcite-quartz veins, breccia and stockwork development within strong silicification.

  • System Type: Epithermal, high-grade, banded, quartz veining, with widespread breccia, and stockwork zones representing an open-pit target
  • Strike-Length: Midnight has an exposed strike length of 650 metres and a width of over 200 metres before being obscured by post mineral gravels in all directions.
  • Structural Geology: The Midnight target is bound by two major north-south trending right-lateral faults in a similar structural setting as the South Jumbo resource. These bounding faults are the Horseshoe, on the west, and the Gold Springs, on the east. Lateral movement along thesestructures created stepover faulting seen cutting through the area of exposed mineralization. In addition, there are shallow east-dipping veins and fractures that could create mineralized, horizontal pipe-like zones where they intersect the vein sets. This is a similar configuration to the higher-grade features seen at the South Jumbo resource.

Geophysics:

There is a strong north-south oriented resistivity high anomaly centered on the Midnight target as identified in the airborne ZTEM geophysical survey. The anomaly extends past the exposed mineralization and to the north it adjoins a strong northeast trending ZTEM resistivity anomaly along which the Thor resource and the Camp Bell target are located.

Geochemistry:

Historical mining in the area was focused on individual quartz-calcite veins up to 2 metres wide that grade up to 57.32 g/t gold with 59.4 g/t silver. Wide areas of brecciation and stockwork vein development are seen in zones of intense silicification. These often produce surface sample results in excess of 0.5 g/t Au and up to 1.42 g/t Au. The Company has conducted extensive sampling in the past, and has collected high-grade veins samples that returned with gold values of up to 57.3 g/t Au gold with 59.4 g/t silver.

In 2020 GRC completed a detailed mapping program with associated surface sampling. Gold results from this work greater than 0.25 g/t Au (cutoff grade of the existing resources at Gold Springs) are listed below followed by past sampling efforts of the Company.
