Grants Creek
This project of 14.7 square kilometres covers the historic Grants Creek Mining Centre, 60 kilometres north east of Halls Creek. Wilsons Reef is a small prospecting licence just to the east of Grants Creek. Like Angelo, the Project is a Joint Venture with Pacrim Energy Ltd.
Previous exploration has largely focussed on the historic workings of the known reefs, with only limited examination on the strike extensions. This style of deposit typically occurs where there is remobilisation of low order strata bound mineralisation into structurally controlled sites during regional deformation events.
Exploration by Metminco has identified the prospective horizon (Perseverance trend), which lies in the clastic sediments of the Olympio Formation, just above the contact of the volcanic dominated Biscay Formation. A thinner mineralised horizon occurs within the Biscay formation, known as the Star of Kimberley trend. Gold mineralisation occurs in glassy blue quartz veins containing abundant pyrite and galena.
Following geological mapping and accompanying geochemical sampling, RC drilling over the first prospect (Perseverance) returned a number of promising intersections. These include 15m @ 4.2 g/t, 5m @ 5.87 g/t, 6m @ 6.13 g/t and 3m @ 7.88 g/t gold, including peak one metre split assays of 17.8 g/t, 20.7 g/t, 12.8 g/t and 15.25 g/t gold respectively. These confirm earlier drilling in the 1980’s over the same area. Down hole survey of the holes would be required to bring the results up to JORC standard.
Grants Creek is viewed as a high grade adjunct to the Angelo Project. Ore could be trucked offsite to the Nicolson’s plant for treatment.
The next site identified for drilling (Moody’s prospect) may be affected by Native Title issues. The Company has received verbal advice that a 500 metre buffer zone is proposed around a landscape feature and Moody’s prospect lies within this buffer.
Future exploration would consist of RC drilling at the Moody’s & Moody’s West prospects and RAB drilling on geochemical anomalies along the main mineralised horizon.
