• Gold explorer Sitka Gold (TSXV:SIG) announced Wednesday (27 Feb) a significant resource update for its flagship RC Gold project in Canada’s northwestern-most frontier of Yukon. The update added a large maiden inferred resource for the Rhosgobel Gold project amounting to 2.25Moz Au @ 0.70 g/t Au – which includes a higher-grade core at surface grading >1g/t to help boost initial cash flows in prospective future operation, and grew the Eiger gold deposit to 0.535Moz Au @ 0.52 g/t. Along with the project’s main Blackjack deposit that was updated last year, this announcement roughly DOUBLES Sitka’s indicated + inferred resources to 5.12 Moz Au, which investors have started to appreciate as they pushed SIG stock up +12% over past week ending 26 Feb (outperforming gold explorer group median +6% by double) to C$1.12/sh, market cap C$416m, and market cap/oz resource now roughly halved from this announcement to US$59/oz Au (now in-line with gold explorer group median $59/oz).

• Gold, copper, and cobalt explorer Doubleview Gold Corp (TSXV:DBG) announced Wednesday (27 Feb) a substantial resource update for its flagship Hat project, in the northwest of Canada’s western-most frontier of British Columbia, which grew gold-equivalent resources by ~64% to 11.96Moz Au at our estimated 3-month trailing average metal prices with no metal recovery factors (50% Au, 42% Cu, 6% Co, 2% Ag), from a reported 609Mt indicated @ 0.21% Cu, 0.18 g/t Au, 0.008% Co and 0.4 g/t Ag (for a reported 0.43% CuEq) and 503Mt inferred @ 0.18% Cu, 0.19 g/t Au, 0.008% Co, and 0.4 g/t Ag (for a reported 0.41% CuEq), which includes a higher-grade central core grading over 0.50% CuEq. And all this excludes additional mineral resources of Scandium Oxide of 4.4 kt Sc2O3 (indicated + inferred). This ~64% increase in resources helped DBG stock rise +75% over past week ending 26 Feb, to C$2.40/sh, market cap C$541m, and market cap/oz resource US$33/oz AuEq ($0.04/lb CuEq) – which is STILL a 44% discount to our 84-company gold explorer median US$59/oz AuEq (and still a slight ~5% discount to 38-company copper explorer group median US$0.042/lb CuEq or $33/oz AuEq).

• Copper developer Gunnison Copper (TSX:GCU) announced Wednesday (27 Feb) an updated PEA for its Gunnison project in Arizona, which supersedes the prior 2024 PEA, and incorporates operational enhancements including addition of high-grade Strong & Harris satellite deposit, material sorting, cement and limestone co-products, and optimization, with average annual production of 174 Mlbs Cu in first 15 years of mine life. These improvements more than offset any cost inflation over the past 1-2 years since the 2024 study, and actually increased the post-tax NPV8 by just over 12% at both our (newly increased) reference copper price US$4.50/lb and our 3-month trailing average Cu price $5.60/lb, leading to P/NAV (market cap/post-tax NPV8 from this study) of 0.10x and 0.062x at both prices respectively – for 48% and 40% discounts to our 34-company copper developer group medians 0.20x and 0.10x, respectively. And this is after GCU stock already rose +15% on this news over past week ending 26 Feb (outperforming copper developer median performance +8% by nearly double), to C$0.61/sh and market cap C$257m. The reported a post-tax NPV8 at US$4.60/lb Cu was US$1.95b from initial capital of US$1.54b (including contingency) with low all-in-sustaining cash costs of US$2.06/lb Cu.

• Lithium clay developer Century Lithium Corp (TSXV:LCE) announced Monday (23 Feb) an updated Feasibility Study for its large flagship Angel Island lithium project in Nevada (formerly Clayton Valley in 2024 FS) which optimized its flowsheet that relies on Direct Lithium Extraction technology – which the jury is still on out among the investment community and for which there are no existing large-scale operations, but for which LCE has validated through a reported four years of pilot plant operations in Nevada. After-tax NPV8% was improved to $4b at Li price assumption $24,000/t Li carb from initial capex of $997m for initial 7,500 tpd options (expands to 15,000 tpd later for another $660m). LCE stock gained +14% over past week ending 26 Feb (outperforming Li clay developer median +7.7% on rising Li price) to C$0.64/sh, market cap C$106m, market cap/t Li carb US$11.6/t ($3/oz AuEq), and P/NAV 0.02x at our estimated at our estimated 3-month trailing average Li price US$17,620/t LCE – in-line with our 9-company Li clay developer group median 0.02x (as same Li price).

• Gold (and silver-lead-zinc) developer Excellon Resources Inc. (TSXV:EXN) announced Monday (23 Feb) a substantial resource update for its past-producing Mallay Silver-Lead-Zinc mine in Peru, that grew indicated silver resources 6-fold, and amounted to 0.89Mt indicated @ 195 g/t Ag, 3.33% Pb, 4.83% Zn and 0.36Mt inferred @ 149 g/t Ag, 2.67% Pb, 4.32% Zn. The project also has a 600 tpd mill that was first commissioned in 2012, and this MRE establishes a higher-confidence inventory to underpin a staged restart plan – while new upside targets are also advanced. But this resource is peanuts in size compared to its other Kilgore project in Idaho, that hosts resources of 0.96 Moz Au and has a 2019, which today’s announced update for Mallay increases to 1.08 Moz AuEq at our estimated 3-month trailing average metal prices. But investors liked the existing mine and mill restart potential associated with this Mallay resource update, and EXN stock rose +27% over past week ending 26 Feb on this news (outperforming gold developer peer group median gain of +11% for same period) to C$0.66/sh, market cap C$226m, and market cap/oz resource US$152/oz AuEq (premium to gold developer median and mean $87 and $137/oz AuEq), but on P/NAV based on 2019 PEA for Kilgore project (which completely excludes this past-producing Mallay mine with restart potential) EXN trades at 0.32x at our reference gold price of US$2,500/oz – a 34% discount to our 77-company gold developer peer group median 0.48x (at same gold price).
