The Zhitong Finance App learned that the Canadian mining company Auro Metals Inc. (TSXV: AURO; OTCQB: AURFF) recently released the latest batch of drilling results for the Santa Barbara gold-copper project in Ecuador. Three of the four holes saw ore from the surface or near-surface, once again verifying the large-scale and highly continuous mineralization characteristics of the porphyry system. The drilled DSB-61 saw 496.5 meters of continuous ore, with an average gold grade of 0.76 g/ton and an average copper grade of 0.12%, including a 212.5-meter high-grade section, with an average gold grade of 1.12 g/t and an average copper grade of 0.14%. This high-grade gold grade is about 115% higher than the resource grade estimated by the resource volume assessment report (0.52 g/ton), setting the highest gold grade record announced by the company so far. Furthermore, the DSB-67 drill hole began to see 380 meters from 76.5 meters below the cover, with an average gold grade of 0.71 g/ton and an average copper grade of 0.1%; the DSB-66 drill hole saw 287 meters from the surface of the earth, with an average gold grade of 0.51 g/ton and an average copper grade of 0.08%. The DSB-65 drill hole revealed the potential for open extension of mineralization in the westerly upward direction.
Victor Feng, CEO of the company, said that the above four drilling results strongly echoed the previous three batches of data, and continued to verify the scale, continuity and grade improvement potential of mineralization in the southern core area of Santa Barbara. In the 496-meter continuous mineralized section of DSB-61, the gold grade is about 46% higher than the estimated resource amount in the assessment report, and the 212 meter high-grade section is more than double the estimated resource volume grade, which will have a positive impact on future resource volume updates. At present, 22 drilling holes have been completed in the first phase of the project in 2026, 14 drilling data have been released, and test results for 8 more holes are yet to be released. The 4 drilling rigs on site continue to operate, and subsequent catalysis is intensive.
Santa Barbara is a large-scale porphyrous gold-copper deposit. According to the NI 43-101 resource assessment, the total resource volume of the project exceeds 235 million tons, including proven resources of 29.8 million tons (0.73 g/ton of gold, 0.10% copper), and the estimated resource volume is 205.7 million tons (0.52 g/ton of gold, 0.09% copper), with a total content of about 128 tons of gold and 224,000 tons of copper. The company recently completed the upgrade from OTC Pink to the OTCQB startup market at the same time, further increasing investor coverage in the US. As deep and upper stage mineralization continues to open up and drilling continues to exceed expectations, there is plenty of room for project resource expansion, and it is expected that Auro Metals will continue to release value revaluation momentum.
