Minsud Resources: Chita Valley Resource Expands to ~4.37Mt CuEq
Context and chronology
Minsud Resources filed a February 20, 2026 effective mineral resource update that re-states the combined inventory at Chita Valley after recent drilling and modelling work. The two deposits sit close to one another and the new estimate consolidates prior studies with 28 additional drill holes, driving a notable re-balance of resource categories. MSR:TSXV presents the MRE on a net smelter return basis using deposit‑specific cut-offs and recoveries; Cube Consulting and GeoEstima compiled the technical inputs and Mr. Michael Job certified the numbers. Mr. Dranovsky positioned the release as evidence the land package is evolving into a large, multi‑metal copper platform, framing the update for investors and potential partners.
The technical outcome is straightforward: the report shows roughly 1,033 kt CuEq in indicated class and about 3,333 kt CuEq inferred across the two deposits, with copper, silver and gold providing most of project value. The enriched porphyry domain at Chita South contributes a narrow but high‑recovery copper envelope; metallurgical recovery assumptions and NSR pricing drive the economic grade calculations. Importantly, modelled mineralization remains open along strike and at depth in multiple domains, while high‑grade breccias are under-drilled—clear targets for follow‑up. Cube’s team applied domain shells tied to sulfide and Mo/Zn‑Pb signatures rather than strict lithological control to improve grade continuity in block estimation.
For markets and partners, the technical numbers re-cast scale: combined CuEq inventory nears 4.37 Mt, and the JV attribution (50.1% South32, 49.9% Minsud) splits that mass almost evenly between the parties. The NSR sensitivity analysis the team used shows copper carrying the lion’s share of value with smaller contributions from silver, gold, molybdenum and zinc. Next operational steps implied by the release are classic: targeted infill and step‑out drilling, expanded metallurgical testing on supergene and primary material, and economic studies to bridge resource to reserve. These tasks will determine whether the updated resource rapidly translates into meaningful capital allocation by the partner with the larger balance sheet.

Copper Giant’s Mocoa Drilling Extends Porphyry Footprint; MD-054 Reveals Stronger Southern Mineralization
Copper Giant concluded its 2025 campaign with two strategic holes that extended the Mocoa porphyry system toward the La Estrella target and returned higher-than-modelled grades at the southern margin. The company’s updated inferred resource now stands at ~1.12 billion tonnes at ~0.51% CuEq, while follow-up infill and permitting work are slated for 2026.
Silver Supply Squeeze Forces Capital Toward Resource-focused Juniors; Americore and Peers Reposition
A pronounced tightening in the silver market has driven the metal above $100 an ounce and shifted investor attention to companies with demonstrable, expandable resources. Exploration-stage firms with nearby infrastructure, recent data sets and active drilling or surveys stand to benefit, though claimed historic resources and paid promotion require independent verification.
Americore Resources: Legacy Drill Data Unlocks Trinity Silver Upside
Americore (AMCO) has recovered overlooked 1980s core and legacy drill logs from its Trinity corridor that include multiple, very wide high‑grade silver intercepts and a near‑surface stockpile inventory that could produce near‑term cash. The development arrives as capital rotates toward auditable, fast‑convertible ounces — supported by policy and market tailwinds — but Americore must still deliver twin‑hole verification, QA/QC and metallurgical results ahead of a Q2 2026 NI‑style resource to fully capture the opportunity.
Lundin Mining’s Vicuña PEA defines a world‑class Argentina–Chile copper‑gold‑silver district
An integrated Preliminary Economic Assessment positions the Vicuña district as a multi‑decade, high‑margin copper, gold and silver development with a base‑case after‑tax NPV of approximately $9.5 billion and an IRR near 15% at conservative metal prices. The staged plan targets early cash flow from a Stage‑1 sulphide concentrator while preserving scale optionality (peak >500 ktpa copper) and outlines funding, infrastructure and permitting pathways across Argentina and Chile.
Metalla posts a standout 2025 as royalty receipts surge and portfolio projects advance
Metalla reported a sharp rise in royalty-derived cash flow for 2025 with attributable gold-equivalent deliveries and top-line receipts well above the prior year. That near-term strength arrives as capital markets rotate toward asset-driven stories and projects that can be rapidly advanced to auditable resources, a backdrop that increases the strategic value of Metalla’s progressing portfolio while leaving execution risk concentrated with third-party operators.
Global critical‑minerals scramble: U.S. $30B mobilization lifts RUA Gold’s New Zealand antimony push
A multi‑instrument U.S. push—reported at roughly $30 billion—has shifted policy from promise to deployment, privileging projects that can demonstrate auditable geology and near‑term metallurgy. That policy backdrop is accelerating RUA Gold’s push in New Zealand, where high‑grade gold‑antimony results and a fortified treasury (C$38M) support an aggressive drill and fast‑track resource timeline.

The company is updating engineering studies, conducting field investigations and pursuing financing and offtake talks ahead of a mid‑2026 feasibility completion target.
Silvercorp closes purchase of Tulkubash–Kyzyltash assets; establishes 70/30 joint venture in Kyrgyzstan
Silvercorp has finalized the acquisition of Chaarat’s Kyrgyz operating vehicle and will convert it into a joint venture with Kyrgyzaltyn, holding 70% and acting as the operator. The company paid $92 million up front and will pay an additional $60 million after obtaining a 30-year mining license extension to 2062.
