Scandinavian Gold (SGL-T) has reported promising results from metallurgical work conducted on a sample from its 100%-owned Keivitsa nickel/copper/platinum-group-element deposit, 142 km northeast of Rovaniemi, Lapland’s capital in northern Finalnd.
A 50 kg sample of core taken from higher-grade material at the centre of the deposit was used in the study. The highest grade concentrate, 15.7% nickel and 58.7 grams total precious metals per tonne, resulted in respective recovery rates of 74.2% and 72.8%. A lower grade concentrate contained 12.2% nickel at a recovery of 80.5% and 34.9 grams total precious metals with a 75.6% recovery (total precious metals include platinum group elements plus gold).
The results provide an idea of the range of concentrate that could be produced using conventional flotation methods. Peter Walker, president of Scandinavian Gold, explained: “These two tests represent the best compromise (between concentrate grade and metal recovery) of the 20 test-runs that were completed.”
SRK Consulting completed a pre-feasibility study for Keivitsa in 2003. The deposit was estimated to contain an indicated 150 million tonnes grading 0.18% nickel, 0.27% copper, 0.01% cobalt, 0.09 gram gold, 0.23 gram platinum, 0.15 gram palladium and 1.23% sulfur and an inferred 315 million tonnes grading 0.18% nickel, 0.29% copper, 0.012% cobalt, 0.08 gram gold, 0.20 gram platinum, 0.12 gram palladium and 1.26% sulfur. The estimate used a 0.10% nickel-equivalent grade cutoff and a 500-metre maximum depth. They postulated that the probable reserve of 120 million tonnes could be open-pitted at a scale of 15 million tonnes per year.
Last year infill drilling at 25-metre spacing in the centre of the deposit intersected higher grade zones up to 1.01% nickel, 1.49 grams platinum and 1.39 grams palladium per tonne over 29 metres. The mineralization is in vertical pipe-like or boudinaged structures trending north. A scoping study is underway to investigate the possibility of selectively mining the high grade portion of the deposit, prior to full scale production.
Metallurgical tests are being conducted by GTK Mineral Processing (a branch of the Geological Survey of Finland). Results are expected in October from a sample taken from the larger lower grade resource.
Tepsa copper-gold project
The 100%-owned Tepsa copper-gold project covers a gravity and electromagnetic anomaly, with a strong copper-gold geochemical signature.
In 2004, a basal till sampling program was carried out over a distance of three km, identifying a gossan over an area 1-km long by 150-300-metres wide. The sampling extended into the weathered bedrock; 198 samples were collected at 50-metre intervals along five lines.
A 1,200-metre diamond drill program will test the 1-km area commencing July 19th.
Scandinavian Gold Prospecting, a wholly owned subsidiary of Scandinavian Gold, holds the properties.
