TNM Drill Down: Great Boulder hits a homerun at Side Well

Our TNM Drill Down features highlights of the top gold assays of the past week. Drill holes are ranked by gold grade x width, as identified by our sister company Mining Intelligence.

This week’s top gold assays come from three corners of the globe: Australia, South America and Africa. Great Boulder Resources leads the rankings for the week of Mar. 24-31 , delivering one of the best drill intercepts of the year to date. On Mar. 27, the Australian company reported that hole 23MBRC006A returned 6 metres grading 589.44 grams gold per tonne from 114 metres depth, for a width x grade value of 3,537. The reverse circulation hole pierced the Mulga Bill prospect near Meekatharra, in Western Australia, as part of a 13-hole first-phase program comprising 3,393 metres. The campaign is designed to test targets in the Central and HGV zones. The company reported two significant intersections of visible gold in the hole. It expects to restart drilling this month to follow up on the initial results from Mulga Bill and the Ironbank prospects. The company also awaits assay results from air core drilling previously undertaken on the six-kilometre-long Mulga Bill corridor.

The second-best gold assay of the week came from Collective Mining and its Guayabales project in Colombia. It reported on Mar. 30 that hole APC-39 returned an intercept of 276.3 metres grading on average 2.12 grams gold per tonne from eight metres depth, for a width x grade value of 586. The hole continued to extend mineralization to the east from drill pad number six as part of a fan pattern of drilling at the Apollo porphyry system. It intersected continuous high-grade copper-silver-gold mineralization from surface. The company reports the hole ended short of the target depth due to a technical issue while in high-grade copper and silver mineralization, with the final 7.6 metres returning 0.7% copper, 152 grams silver per tonne and 0.46 grams gold per tonne. Hole APC-39 is the easternmost completed hole with assay results available, drilled from drill pad six. It has extended the strike length of high-grade mineralization at depth from the previous hole APC-35 to 125 metres.

The third-best drill assay for the week comes from Montage Gold, which reported that hole GBDD030 at the Koné project in Ivory Coast returned 233.7 metres grading 2.08 grams gold per tonne from surface, for a width x grade value of 486. On Mar. 27, the company said the hole was part of an ongoing resource expansion program targeting the Yeré North and Gbongogo South deposits. A concurrent diamond drill program continues at the Gbongogo Main deposit, confirming and expanding the resource base, with the most recent deep holes ending in mineralization.
