Red Gate (GOLD)

Red Gate Project

The Red Gate Project is a gold project located approximately 140km north of Kalgoorlie, the project is held within 1 granted Exploration Licence covering a total area of 145.2km2

The project has had historic exploration by both Blackstone Minerals and previous tenement holders. Historic work predominantly focused on the Porphyry North prospect, this included RAB, AC and RC drilling targeting gold. On a more regional note there has been numerous airborne and ground geophysical surveys. Mineralisation that has been encountered in historical work shows an intimate relationship between the alteration, pyrite and gold. Gradient array induced polarisation (GAIP) was completed by historic owners (Sons of Gwalia) and showed a positive correlation between chargeability and mineralisation.

The Prospects at Red Gate include:

The Red Gate Project Tenements and prospects on interpreted geology.

PORPHYRY WEST

Porphyry West has shown gold mineralisation associated with quartz veining and pyrite at the lower contact of a granitic intrusive and mafic rocks. The mineralisation is poorly tested and recent drilling has returned exceptional results including:

  • 23m at 3.82g/t Au from 14m down-hole in hole RGRC002, including: 
    • 5m at 14.29g/t Au from 27m
  • 1m at 5.75g/t Au from 15m down-hole in hole RGRC003
  • 24m at 1.04g/t from 42m down-hole in hole RGRC003
  • 1m at 21.35g/t from 80m down-hole in hole RGRC011

(Note all widths are down-hole width, true width not known)

GRUNTERS

Grunters was identified as a soil geochemistry anomaly that received its first drilling in November 2021. The drilling intersected granites with some quartz veining and minor pyrite, the best results in this greenfield drilling included

  • 8m at 0.57g/t Au from 20m down-hole in hole RGRC016
  • 4m at 0.36g/t Au from 32m down-hole in hole RGRC015

PORPHYRY NORTH

Historical work at Porphyry North has identified a small contiguous zone on mineralisation around two historical shallow shafts. The drilling is constrained to a small zone that is well defined, Codrus Minerals will investigate if there is the opportunity for more mineralisation to be found at depth and down plunge.

PORPHYRY EAST

Historical work has identified a narrow zone of gold mineralisation that extends over 600m. Structural modelling will take place to target potential zones of dilation and thickening of mineralisation.  

ARIETA and VONU

The Arieta and Vonu were identified through Induced Polarisation surveying. Initial shallow drill testing has not identified mineralisation to date and further work is required to understand the cause of the chargeability anomaly.

Historic drilling at Porphyry West includes:

  • 12m at 9.16g/t Au from 8m down-hole in hole NPRC030
  • 15m at 1.13g/t Au from 22m down-hole in hole NPRC071

BSX had previously completed a further 2.5d pole-dipole IP (2.5dIP) survey based on the success of the historic GAIP surveys. Three chargeable bodies of interest were identified in the survey:

  • PN1, a shallow, moderately chargeable body coincident with known and well drilled Porphyry North gold mineralisation
  • PN2 a moderately chargeable, resistive body partly coincident with the reconnaissance drilled Porphyry West prospect
  • PN3 a deep, broad moderately chargeable, resistive body at 300–400m depth to the southwest and possibly loosely connected with Porphyry West. This anomaly is poorly constrained (Cooper, 2020) and now referred to as the Conto Springs target.
