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 (OROXF) announced the closing of its previously announced private placement, raising C$16 million in gross proceeds. The total includes C$2 million from full exercise of the agent's option. The company sold 50,000,000 units at C$0.32 each, comprising one common share and half a warrant. Each whole warrant permits purchase of one share at US$0.32 for 24 months after closing.
Orosur intends to use net proceeds principally to advance its Anzá exploration project in Colombia and expects the funding to last into late 2027. Red Cloud received C$520,000 in cash commission; U.K. brokers received £239,760, approximately C$451,600, in commissions and fees. AIM admission of the new shares is expected on or around October 7, 2026. Voting shares will total 452,196,324 following issuance. The closing remains subject to final TSX Venture Exchange approval.
Orosur Mining (OTCQB: OROXF) reported accelerated exploration at its 100%-controlled Anzá gold project in Colombia, now covering approximately 530km² (170km² of granted titles and 360km² of applications). The company has commenced the first-ever drilling at the El Cedro gold-copper porphyry prospect, with hole CED001 targeting 500m after intersecting porphyry intrusion with stockwork veining and alteration.
At Pepas West, shallow oxide mineralisation continues to be defined, including 19.45m at 1.02 g/t Au from surface in PEP106 and 7.6m at 0.47 g/t Au in PEP107. At APTA, hole MAP108 intersected 78.95m at 0.38 g/t Au, improving understanding of structural controls. An auger drilling program to ~10m depth is being trialled at Pepas West to sample surficial material and potentially support future resource classification. According to Orosur, three drill rigs are now operating concurrently at Pepas, APTA and El Cedro.
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.
Orosur Mining (OTCQB:OROXF, TSXV:OMI, AIM:OMI) has published its block listing six‑monthly return for unlisted warrants under AIM Rule 29 and Schedule Six, covering the period from 14 January 2026 to 13 July 2026.
