A rare earths property in British Columbia’s Rocky Mountain rare metal belt gains new attention as Canadian International Minerals TSXV:CIN takes another look at previous assays. An 11-hole program on the Wicheeda alkaline-carbonatite project in 2011 targeted rare earths but the company didn’t consider the niobium results to be material info. On January 26, however, CIN released niobium assays from four 2011 holes, with highlights showing:
- 0.188% Nb2O5 over 16.06 metres, starting at 171.8 metres in downhole depth
- (including 0.27% over 6.3 metres)
- (which includes 0.731% over 0.98 metres)
- 0.156% over 24.43 metres, starting at 173.23 metres
- (including 0.217% over 9.57 metres)
- (which includes 0.337% over 3.9 metres)
- 0.226% over 37.6 metres, starting at 232.98 metres
- (including 0.297% over 18.27 metres)
- (which includes 0.321% over 8.48 metres)
- (which includes 0.632% Nb2O5 and 158 ppm tantalum over 2.2 metres)
True widths weren’t available.
Formerly called the Carbo project, Wicheeda showed RE results in the range of 0.2% to 0.5% total rare earth oxides in most of the 11 holes sunk during 2011. The previous year’s campaign found significant RE mineralization in all nine holes, with one intercept hitting 1.43% TREO over 37.3 metres.
Adjacent to CIN’s Wicheeda, Spectrum Mining’s Wicheeda project holds an inferred 11.3 million tonnes averaging 2.5% TREO.
CIN noted two niobium deposits hosted in the Rocky Mountain rare metal belt. The Upper Fir deposit on Commerce Resources’ (TSXV:CCE) Blue River project holds an indicated 48.41 million tonnes averaging 0.161% Nb2O5 and 197 ppm Ta2O5. Located about 330 kilometres southeast of Wicheeda, Upper Fir also holds an inferred 5.4 million tonnes averaging 0.176% Nb2O5 and 191 ppm Ta2O5.
About 240 kilometres northwest of Wicheeda, Taseko Mines TSX:TKO brought the Aley project to pre-feas in 2014 with proven and probable reserves of 83.8 million tonnes averaging 0.5% Nb2O5.
CIN stated it “continues to re-evaluate the exploration targets for the Wicheeda project and will be investigating a number of partnership avenues in the coming weeks.”
In November the company released sample results from a due diligence program on its proposed Tisova acquisition, a former copper-polymetallic mine in the Czech Republic.
