Widely spaced drilling on the Boleo copper-cobalt property in Baja California Sur, Mexico, is returning more copper-cobalt values for International Curator Resources (TSE).
The drilling includes 21 holes in three zones outside the main area of focus on the property.
Fifteen holes, spaced on roughly 500-metre centres in the Rancheria and Montado areas, returned an average of 2.2% copper and 0.093% cobalt over 2.62 metres. (These areas cover a contiguous area of 6 sq. km toward the southeastern end of the property.)
Eight holes on the San Luciano zone, which is separated from the Rancheria and Montado zones by a 1-km-wide area of lower-grade material, returned an average grade of 2.47% copper and 0.132% cobalt over 2.5 metres.
Mineralization at Boleo is hosted in flat-lying, sedimentary beds extending over an area roughly 12 km long by 2 km wide.
Average values from Rancheria, Montado and San Luciano are all from the No. 1 bed which, in that area, lies 70-250 metres below surface.
Curator’s main focus of drilling has been to the northwest, on the nearer-surface, potentially open-pit resources at Saturno, Dos de Abril and Mercurio.
The company is conducting infill drilling on the near-surface resources as part of an ongoing feasibility study for a copper-cobalt leaching operation.
At last report, the Boleo resource stood at 373.8 million tonnes grading 0.96% copper and 0.071% cobalt based on a cutoff grade of 1% copper-equivalent.
