| Filed | Company | Filing type | Summary | Source |
|---|---|---|---|---|
| Anteros Metals Inc. | NI 43-101 Technical Report | Anteros Metals Inc. (CSE: ANT) voluntarily filed a NI 43-101 technical report (effective June 29, 2026; authored by Geoff Heggie, PhD, P.Geo.) for its Seagull Critical Minerals Project in Ontario, covering targets for natural hydrogen, helium, and platinum-group element (PGE) mineralization within the Midcontinent Rift intrusive complex. The report was filed proactively rather than in response to a material change or prospectus, providing investors independent technical validation ahead of the company's planned Phase 2 drilling mobilization. The Seagull Project's dual-commodity positioning—natural gas plus PGE-bearing magmatic sulphides—differentiates it from conventional junior miners and could attract cross-sector institutional interest. | Filing | |
| Surge Copper Corp. | NI 43-101 Technical Report | Surge Copper Corp. (TSX-V: SURG) filed its NI 43-101 Technical Report and Pre-Feasibility Study for the Berg Copper Project in central British Columbia on July 30, 2026, prepared by Ausenco Engineering Canada and Moose Mountain Technical Services. The PFS delivers an after-tax NPV₈% of C$4.6 billion, an IRR of 24%, and a 2.9-year payback on initial capital of C$4.7 billion, underpinning a 28-year open-pit mine producing 8.6 billion pounds of copper equivalent. At a time of structural copper deficit, this is one of the largest undeveloped copper PFS results in Canada and positions Berg as a major institutional and potential strategic acquisition target. | Filing | |
| Lithium Africa Corp. | NI 43-101 Technical Report | Lithium Africa Corp. (TSXV: LAF, OTCQB: LTAFF) received South African Section 11 consent on July 27, 2026, formally completing its 70% acquisition of Namli Exploration and Mining—holder of the 1,675 km² Springbok Lithium Project including a past-producing lithium pegmatite mine—and simultaneously filed a NI 43-101 Technical Report on SEDAR+ consolidating historical and company exploration data. A 3,500 m drill program is actively underway at Springbok. The dual catalyst of regulatory approval and an independent NI 43-101 technical report significantly de-risks the flagship asset and positions the company to attract institutional capital in a market hungry for quality early-stage lithium drill stories. | Filing | |
| Resouro Strategic Metals Inc. | NI 43-101 Technical Report | Resouro Strategic Metals Inc. (TSX-V: RSM; ASX: RAU) filed an NI 43-101 Preliminary Economic Assessment technical report for the Tiros Titanium and Rare Earths Project in Minas Gerais, Brazil, dated July 29, 2026 (effective July 10, 2026), prepared by Norda Stelo Inc. The PEA outlines an after-tax NPV₈% of US$714.9 million and an IRR of 44.2%, with the project combining titanium oxide and rare earth elements (REE) production in a jurisdiction with established mining infrastructure. Strong economics and dual-commodity REE+Ti positioning make this report a significant capital-markets catalyst for RSM as institutional interest in non-Chinese REE supply intensifies. | Filing | |
| Integra Resources Corp. | NI 43-101 Technical Report | Integra Resources Corp. (TSX-V: ITR) filed a Feasibility Study and updated Life of Mine Plan NI 43-101 Technical Report for the operating Florida Canyon Gold Mine in Pershing County, Nevada, dated July 28, 2026 (effective May 31, 2026), prepared by Global Resource Engineering Ltd. and filed on both SEDAR+ and EDGAR. The study shows a 74% increase in Proven and Probable Mineral Reserves, a 17% rise in annual gold production, mine life extended to 2033, and after-tax free cash flow exceeding US$800 million (NPV US$601 million base case; US$723 million at spot gold ~$4,200/oz). For a producing TSX-V gold issuer, this scale of reserve upgrade and FCF projection materially enhances financing capacity and M&A optionality. | Filing | |
| Canadian GoldCamps Corp. | NI 43-101 Technical Report | Canadian GoldCamps Corp. (CSE: CAMP) filed an independent NI 43-101 Technical Report on SEDAR+ for its Mercator Gold Project — a 113-claim, ~58.6 km² property in the Caniapiscau District of northeastern Québec — on July 28, 2026. Filing was required upon Mercator becoming CAMP's primary mineral project after the company optioned it from Stelmine Canada Ltée for up to an 80% interest. Approximately 82% of 111 high-resolution samples returned gold above detection limits, validating the gold and critical minerals system as a drill-ready target. | Filing | |
| McEwen Inc. | NI 43-101 Technical Report | McEwen Inc. (TSX/NYSE: MUX) filed NI 43-101 Technical Reports on July 22, 2026 for the Grey Fox Prefeasibility Study (effective June 8, 2026, report date July 17, 2026) in Ontario and for the Lookout Mountain and Windfall Mineral Resource Estimates in Nevada. The Grey Fox PFS underpins Probable Mineral Reserves of 9.41 Mt at 3.24 g/t Au containing 980,300 gold ounces and extends Fox Complex production through 2041—a 15-year mine life providing significant reserve visibility. These filings provide the regulatory foundation for potential construction financing decisions and materially derisk the Fox Complex expansion as a standalone production centre. | Filing | |
| West Red Lake Gold Mines Ltd. | NI 43-101 Technical Report | West Red Lake Gold Mines Ltd. (TSXV: WRLG) filed on SEDAR+ an NI 43-101 Technical Report dated July 22, 2026 (effective June 1, 2026) for the updated Rowan Mineral Resource Estimate and a maiden MRE for the Mount Jamie deposit, both in the Red Lake Gold District of northwestern Ontario, prepared by independent consultants Sims Resources LLC and Fuse Advisors Inc. Non-material adjustments from previously disclosed figures reflect final block-proportioning and rounding reconciliation. This filing consolidates the resource base at Rowan-Mount Jamie, advancing the company's multi-deposit strategy alongside the Madsen Mine and Fox Complex gold assets in Canada's most prolific gold camp. | Filing | |
| Orosur Mining Inc. | NI 43-101 Technical Report | Orosur Mining Inc. (TSXV: OMI) filed on SEDAR+ an NI 43-101 Technical Report dated July 13, 2026 (effective May 15, 2026) for the El Pantano early-stage gold/silver exploration project in Santa Cruz Province, Argentina, after completing 24 diamond drill holes totaling 5,533 m on a low-sulphidation epithermal system. The filing confirms Orosur now holds 100% of El Pantano following completion of all JV obligations, removing the partner risk that previously clouded the asset. The report positions El Pantano for a resource estimate campaign or joint-venture/asset-sale process, adding a fully owned precious-metals target in Argentina to Orosur's portfolio. | Filing | |
| Salazar Resources Limited | NI 43-101 Technical Report | Salazar Resources (TSXV: SRL) published an independent NI 43-101 Technical Report (SRK Consulting, effective December 31, 2025) for the Curipamba-El Domo polymetallic project in Ecuador, reporting an after-tax NPV (8%) of US$573 million — a 121% increase vs. the 2021 feasibility study — and a 45% IRR; Silvercorp holds 75% and operates, Salazar holds a 25% carried interest. The dramatically improved economics reflect higher copper and precious metals prices and engineering optimization, significantly re-rating Salazar's carried interest. The updated economics materially increase the probability of a near-term construction decision. | Filing | |
| Rio2 Limited | NI 43-101 Technical Report | Rio2 Limited filed an independent NI 43-101 Technical Report on SEDAR+ on July 14, 2026 for the Kalzas Tungsten Project in Yukon, Canada, supporting historical data, geology, and exploration potential. Tungsten is a federally designated Canadian critical mineral and a key input in advanced manufacturing and defence applications. This filing establishes the qualified-person-reviewed technical baseline required to advance future financing and partnership discussions for the asset. | Filing | |
| Lode Gold Resources Inc. | NI 43-101 Technical Report | Lode Gold Resources Inc. (TSXV: LOD) filed an NI 43-101 Technical Report on SEDAR+ on July 8, 2026, for the Fremont Gold Mine (Mariposa County, California), establishing 19.9 Mt indicated at 1.79 g/t (1.15 Moz Au) and 38.5 Mt inferred at 1.73 g/t (2.17 Moz Au) at a 0.82 g/t cut-off. The Fremont is a brownfield project with 43,000m of prior drilling, 14 adits, and 2 shafts — the formal 43-101 underpins subsequent financing activity (the upsized $9M PP closed July 22) and validates the resource for potential restart. | Filing | |
| Lode Gold Inc. | NI 43-101 Technical Report | Lode Gold Inc. (TSXV: LOD) filed an NI 43-101 Technical Report for the Fremont Gold Mine on SEDAR+ on July 8, 2026, providing the qualified-person-reviewed technical disclosure required under National Instrument 43-101.

| Torex Gold Resources Inc. | NI 43-101 Technical Report | Torex Gold Resources (TSX: TXG) filed the NI 43-101 Technical Report and Preliminary Economic Assessment for the Los Reyes gold-silver project in Sinaloa, Mexico on SEDAR+ on July 7, 2026 (effective date April 25, 2026), showing after-tax NPV of US$1.5 billion and IRR of 37%, with average annual production of 134 koz AuEq (93 koz Au + 2,992 koz Ag) over a 14.4-year mine life financed entirely from internal cash flow. The exceptional PEA economics at Los Reyes establish it as a major potential brownfield growth catalyst and possible standalone project or strategic M&A target within Mexico's gold-silver corridor. | Filing | |
| Mako Mining Corp. | NI 43-101 Technical Report | Mako Mining (TSXV: MKO; Nasdaq: MAKO) announced NI 43-101 Proven and Probable Mineral Reserves of 597,744 oz Au and 6.30 Moz Ag (0.327 g/t Au, 3.45 g/t Ag in 56.8 M tonnes) at the Moss Mine in Arizona, with post-tax NPV5% of US$254 million and a 15-year mine life at US$3,500/oz Au and US$50/oz Ag; average annual production is 30,900 oz Au through 2039. The technical report will be filed on SEDAR+ within 45 days. This first formal reserve statement gives Moss Mine institutional-grade credibility as a long-life gold-silver asset with significant near-term production upside. | Filing |
