Most drill results get reported in grams per tonne. This week one company reported one in kilograms, and it took a moment to register that 29,620 grams per tonne and 29.62 kilograms per tonne are the same absurd number. Two copper stories landed the same week too, one in a Sonora skarn where the ore minerals visibly darken with grade, the other in a Minnesota titanium deposit where every single hole drilled this year has come back mineralized.
Silver Tiger Metals Intersects 7,715 g/t Silver Equivalent in the Caleigh Vein at El Tigre, Sonora
Silver Tiger Metals Inc. (TSX: SLVR; OTCQX: SLVTF) reported on September 11 exploration results from the Northern Area of its El Tigre silver-gold project in Sonora, Mexico, with hole ET-26-649 in the Caleigh Vein returning 2.1 metres grading 7,715.1 g/t silver equivalent, including 0.53 metres at 29,620 g/t silver equivalent. A separate hole in the Protectora Vein, ET-26-643, returned a much broader 93 metres at 70.1 g/t silver equivalent.
The company calculates its silver equivalent using a simple 75:1 silver-to-gold price ratio rather than current spot prices for each metal individually. These Northern Veins, including Caleigh, Protectora, and several newly discovered structures, sit outside El Tigre’s currently defined resource and mine plan. Silver Tiger is in the middle of building a heap leach mine at El Tigre, with a first gold-silver doré pour targeted for December 2027, so this exploration work is aimed at extending the project’s life well beyond what is already permitted and under construction. The company’s market capitalization has grown into the CA$290 to CA$450 million range over the past year, making it the largest name covered in this roundup.
Algo Grande Copper Hits 15.8% Copper Equivalent in a Skarn Discovery at Cerro Grande, Mexico
Algo Grande Copper Corp. (TSXV: ALGR; OTC: ALGRF) reported on September 11 the first Phase II assay results from its Cerro Grande skarn discovery at the Adelita Project in Sonora, Mexico, with hole AG-CG-PH2-002 intersecting 30.23 metres grading 1.5% copper equivalent, including a 3.55-metre high-grade core at 9.4% copper equivalent and a narrower 1.2-metre interval at 15.8% copper equivalent, hosted in garnet skarn with bornite, chalcopyrite, and abundant chalcocite. The intercept sits roughly 100 metres shallower than mineralization the company reported from its first drill campaign, expanding the zone that can realistically be targeted.
The company has separately disclosed a marketing agreement worth up to EUR 250,000 with an arm’s length European investor-relations firm, running from September through March 2027, covering advertorial content and an investor awareness campaign targeted at European retail investors. That spending has no connection to this publication’s coverage, but it is worth knowing when reading anything else written about this stock. No formal resource estimate exists yet at Cerro Grande; Phase II drilling is planned to run to roughly 7,200 metres across 15 holes, testing the discovery along a 2.5-kilometre magnetic corridor. Algo Grande’s market capitalization sits near CA$25 million.
Green Bridge Metals Extends Titanium-Copper Mineralization in Minnesota, Six for Six on the Season
Green Bridge Metals Corporation (CSE: GRBM; OTCQB: GBMCF) reported on September 10 final assay results from its six-hole Phase 1 program at the Titac South target of its South Contact Zone Project in northeastern Minnesota, with hole TS26-004a intersecting 195.0 metres grading 0.25% copper and 10.18% titanium dioxide, including 62.0 metres at 0.29% copper and 10.54% titanium dioxide. A step-out hole testing a previously untested geophysical anomaly, TS26-007, also returned mineralization, 12.0 metres at 0.20% copper and 8.33% titanium dioxide.
All six holes drilled at Titac South this season returned sulphide mineralization, a detail the company is using to justify accelerating its Phase 2 program ahead of schedule, with a scoping study now targeted for the end of 2027. Titac South already carries an Inferred resource of 46.6 million tonnes grading 15% titanium dioxide, so copper is effectively a credit the company is now trying to bring into that resource rather than the main event. True widths at Titac remain undetermined given the irregular geometry of the mineralized zones. Green Bridge’s market capitalization sits near CA$44 million.
Frequently Asked Questions
Construction continues on the heap leach mine, with first doré pour targeted for December 2027. Exploration on the Northern Veins is ongoing alongside mine construction, aimed at extending the project beyond its current mine plan.
The Phase II program is planned to reach approximately 7,200 metres across 15 holes, systematically testing the 2.5-kilometre magnetic corridor identified by the company’s drone survey, with further assays expected as remaining holes are logged and analyzed.
The company says details of the accelerated Phase 2 program, which will target bringing copper into the existing titanium resource and expanding it at Titac North, will be announced shortly.
Green Bridge Metals’ Titac South already carries an Inferred titanium resource that this drilling is working to add copper credits to. Silver Tiger Metals’ Northern Veins sit outside El Tigre’s existing resource and mine plan. Algo Grande Copper’s Cerro Grande discovery has no resource estimate yet.

Silver Tiger Metals’ silver equivalent figures use a fixed 75:1 silver-to-gold price ratio rather than individually sourced spot prices; equivalent grades should not be read as a substitute for the individual metal grades reported alongside them. Algo Grande Copper has disclosed a marketing and investor-awareness agreement with an arm’s length European IR firm worth up to EUR 250,000 running through March 2027; this arrangement is unrelated to aktiego.com’s coverage but is disclosed here for transparency. Green Bridge Metals’ Titac South project carries an existing Inferred titanium resource that this drilling seeks to add copper credits to; reported intervals are not true widths given the irregular geometry of the mineralized zones. Algo Grande Copper has no resource estimate at Cerro Grande and is a micro-cap security carrying elevated volatility and financing risk typical of exploration-stage issuers.
