Lithium-cesium-tantalum pegmatite projects are being advanced on simplified grade models that ignore strong mineralogical zoning, with cases such as Mount Marion showing fine-grained spodumene and high mica contents can destabilise DMS media, depress concentrate grades and force costly plant retrofits. At Canada’s Tanco pegmatite, assuming a uniform 60:40 spodumene–quartz intergrowth and overlooking iron and phosphate phases contributed to inefficient plant design and shutdowns. Patriot Battery Metals’ Shaakichiuwaanaan feasibility study similarly relies on a 1D Li₂O recovery formula, without 3D modelling of mica, arsenic and antimony domains that could flag low-density clay-rich zones and DMS underperformance.

Metals are now trading as “stock puppets”, with Bloomberg Intelligence senior commodity strategist Mike McGlone warning that copper closely shadows US equity moves, potentially falling 20–30% if a “normal” 10% stock market correction occurs. He cautions that current gold enthusiasm looks “too peakish”, arguing investors should “be selling when they’re yelling” rather than treating bullion as a one-way hedge. McGlone links the Fed’s latest rate hike to US checks and balances, expecting equity weakness to be the first clear signal of a shift from inflation to deflation.

Lundin Gold has reported record grades at its Fruta del Norte district in Ecuador, including a 3-metre Bonza Sur intercept grading 204.26 g/t gold from 140 m, with a 60 cm sub-interval at 1,035.60 g/t, and 5.5 m at 13.75 g/t gold and 50.8 g/t silver from 715 m in hole BLP-2026-483-D2. The newly defined Quebrada Dorada vein system, 2 km south of Bonza Sur, has returned 13 m at 6.53 g/t gold from ~195 m and extends mineralisation over 2.7 km, open to the south. With three rigs at Bonza Sur and two at Quebrada Dorada, Lundin is targeting higher-grade zones adjacent to existing Fruta del Norte South underground development to extend the current 12-year mine life and build on 5.85 Moz of proven and probable reserves.
