Orosur Mining Inc. reports as a minerals explorer and developer with operations in Colombia and Argentina. Company news centers on exploration at the 100%-owned Anzá Project in Colombia, including Pepas deposit mineral-resource work, NI 43-101 technical reporting, soil sampling, aeromagnetic surveys, and drilling across targets such as El Cedro and APTA.
Recurring updates also cover Argentine exploration at the El Pantano Project, quarterly financial results and MD&A filings, common-share issuances tied to warrant or RSU exercises, and total voting-rights disclosures for its AIM and TSX Venture-listed shares.
Orosur Mining (OTCQB:OROXF) reported new drill results from the Pepas West prospect at its Anzá gold project in Colombia, including near-surface intercepts such as 10.2m @ 5.77g/t Au (PEP103) and 19.8m @ 1.77g/t Au (PEP104), all starting from surface.
The six holes (PEP100–PEP105) outline an extensively weathered, flat-lying oxide gold zone, which Orosur interprets as roughly 10m thick over a wide area and locally obscured by thin barren cover. The company plans to trial a smaller auger rig to rapidly define this surface mineralisation, while keeping a diamond rig on site for deeper drilling around Pepas West and other targets. Orosur views this free-digging, surficial gold as a high priority in a potential near-term production scenario.
Orosur Mining (OTC: OROXF) reported 2025–26 exploration results from its early-stage El Pantano gold/silver project in Santa Cruz, Argentina, and confirmed it has now earned 100% ownership under its joint venture with Deseado Dorado.
The company has completed the required US$3m in JV expenditures (US$1m in Phase 1 and US$2m in Phase 2, ahead of deadline) over a 560km² licence package. Deseado retains a 2% NSR on future production, of which 1% may be repurchased by Orosur for US$1m. The maiden drill program comprised 24 diamond holes totaling 5,533m, testing a rift-related, low-sulphidation epithermal model.
Drilling at El Pantano West intersected multiple gold-bearing intervals, including 18.0m at 0.46 g/t Au (DH_ELP003) and several broad anomalous zones up to 27.0m at 0.14 g/t Au (DH_ELP023), interpreted as structurally controlled vein corridors. El Pantano East returned broad arsenic pathfinder intervals beneath a silica cap, supporting a higher-level epithermal environment. A NI 43-101 Technical Report dated 13 July 2026 has been filed, and Orosur plans to design the next exploration phase over the coming winter.
Orosur Mining (OTCQB:OROXF) reported new drilling results from the APTA prospect at its Anzá gold project in Colombia. Second hole MAP107 returned a composite intersection of 135.5m at 1.91 g/t Au from 111.65m to 247.15m, including 49m at 4.06 g/t Au, 26m at 7.15 g/t Au and 13.8m at 12.73 g/t Au.
MAP107 entered mineralisation higher in the Aragon fault zone than historic holes and was terminated early in broken ground, but still ended in mineralisation. According to Orosur, results indicate the deeper high‑grade zone at APTA may be more extensive and will guide geological modelling that could support a future Mineral Resource Estimate if further drilling justifies it. Due to difficult conditions, the rig is being moved east to start hole MAP108 testing shallower mineralisation within days.
