USGS releases first study to assess global earthquake risk to mineral supplies
Earthquakes have the potential to substantially affect mining operations, leading to supply chain disruptions that adversely affect the global economy.
Great Bear Resources of Vancouver has hit grades as high as 30.15 g/t gold over 7.25 metres during drilling at its 100% owned Dixie project in the Red Lake District. Both the Dixie Hinge zone (DHZ) and Dixie Limb zone (DL) were drilled, sometimes with a single hole providing core from both zones.
At the DHZ hole 031 intersected four gold veins along a 141-metre wide zone of increased quartz veining and alteration. That hole returned three notable vein intersections: 7.3 metres of 30.15 g/t gold, including 1.5 metres of 130.49 g/t; 4.0 metres of 11.72 g/t gold; and 0.5 metre of 60.72 g/t gold. Of the 42 drill holes completed along the strike length of the DHZ, 26 of them cut intervals with more than 15 g/t gold.
Highlights from the DL zone included 39.2 metres of 2.07 g/t gold starting at approximately 25 metres below the surface. Included in that intersection were 9.2 metres of 5.43 g/t gold that in turn included 0.7 metre of 20.46 g/t gold.
Great Bear’s current drill program includes 30,000 metres to be completed this year. A second drill rig has been added on the property to speed up the program.
