Orosur Mining Announces Anza Activity Accelerating
Orosur reports modest new gold intercepts at El Cedro, while the first hole remains visual only.
Orosur Mining Inc. released an operational and exploration update rather than a single high-grade drill-result announcement. First-ever drilling at the El Cedro project began in late August 2026. Hole CED001 immediately intersected a porphyry intrusion characterized by stockwork veining, silicification, and potassic alteration. The company plans to drill 500 m over approximately five weeks, though no assays are currently reported.
The total Anza project area has increased to roughly 530 km2, comprising 170 km2 in granted titles and 360 km2 under application. At Pepas West, two shallow holes were reported. PEP106 returned 19.45 m at 1.02 g/t Au from surface, including 2.25 m at 3.11 g/t and 1.1 m at 3.09 g/t. PEP107 returned 7.6 m at 0.47 g/t Au from surface. Additionally, APTA hole MAP108 returned 78.95 m at 0.38 g/t Au from 134.8 m to 213.75 m.
Orosur is trialling auger drilling at Pepas West for shallow unconsolidated material. Three rigs are currently active: one at Pepas, one at APTA, and one at El Cedro.
Orosur Mining Inc. remains a pre-revenue explorer, with its material value driven by exploration results and the small Pepas maiden resource rather than earnings. This release does not change the known scale, grade, or confidence of any resource.
El Cedro represents the most significant new event as the first drill test of a large porphyry system, though it serves only as an activity update without assays. Pepas West results were in line-to-weak compared with the high-grade Pepas West holes reported in August and April 2026. MAP108 was a low-grade APTA hole; it does not damage the APTA thesis because it was drilled off-section and appears to have been a structural reconnaissance hole, but it also adds no value.
The stock is near its 52-week low at about C$0.28, down from a high of C$0.72 in January 2026. The market has not re-rated for the earlier APTA or Pepas West intercepts, so there is no embedded high-grade anchor that this release disappoints in a material way. Taken together, this is ordinary exploration news flow with a potential future catalyst in El Cedro, but no transformatively new drilling data.
Orosur Mining Inc. is a gold explorer listed on the TSXV and AIM with assets in Colombia and Argentina. Its primary asset is the Anza project in Colombia, which is 100% owned through Minera Anza and Minera Monte Aguila. The Anza area encompasses Pepas, which hosts a maiden 43-101 resource of approximately 219,000 oz of gold; APTA, a high-grade epithermal system with about 40,000 m of historical drilling; and El Cedro, an untested gold-copper porphyry cluster. The total project area now covers approximately 530 km2, including pending applications.
In Argentina, Orosur owns the El Pantano low-sulphidation epithermal project, where initial drilling returned only low-grade gold intervals. According to the latest financial statements, the company holds US$13.66 million in cash, US$23.6 million in total assets, and US$5.67 million in total liabilities, with negative operating cash flow and no revenue. The latest reported share count is approximately 395.95 million shares.
