G50 Corp hits high-grade antimony with gold at Nevada’s White Caps; next drilling program set

Key highlights:
 

• Maiden 2025 RC program: 3.5% antimony (Sb) peak in hole WCRC25-007, within 6.1m @ 1.58 g/t Au, 1.69 g/t Ag, 1.1% Sb from 74.7m.
• Multiple gold hits: 22.86m @ 0.92 g/t Au (WCRC25-003)*; 15.24m @ 0.75 g/t Au (WCRC25-011); plus near-surface intervals in other holes.
• Why it matters: First angled drilling at White Caps supports the geological model and opens follow-ups near a historic 30 g/t Au mine.
• Outlook: 2,000m core program planned to extend mineralisation and test new targets along the Reliance Fault trend. 
   

A measured, data-driven update for a fast-moving small cap

G50 Corp (ASX: G50) advanced at midday trading after releasing results from its maiden 2025 RC drill campaign at the White Caps Project in Nevada’s Manhattan district—an area flanked by the past-producing Manhattan Gold Mine and about 20km south of Round Mountain, one of America’s largest gold operations. The stock sits near the top end of its 52-week range after a year of strong relative performance, reflecting growing investor interest in gold and critical minerals exposure in tier-one jurisdictions. 

What the announcement says

The standout datapoint was antimony: hole WCRC25-007 returned a peak 3.5% Sb (35,000 ppm) at 77.7–79.2m, part of a broader 6.1m zone grading 1.58 g/t gold, 1.69 g/t silver and 1.1% Sb from 74.7m. Other notable intervals include 22.86m @ 0.92 g/t Au from 67m in WCRC25-003 (noting a 6m mined-out void counted at zero grade within that interval), 15.24m @ 0.75 g/t Au in WCRC25-011, 10.67m @ 0.46 g/t Au in WCRC25-010, and 4.57m @ 0.68 g/t Au in WCRC25-009. Three of four wide-spaced target areas returned shallow gold; silver was logged in most holes; and pathfinder elements—arsenic and antimony—correlate with the precious-metal results. 

Importantly, this was the first angled drilling at White Caps; most 1980s holes were vertical, which the new work suggests may not have optimally tested steep structures thought to control higher-grade shoots. The company’s assays and logging point to gold within silicified and decalcified limestone, with steep-dipping faults acting as fluid conduits—classic Carlin-style signatures for the district. 

Why antimony alongside gold is noteworthy

Antimony (typically as stibnite) is a strategic mineral used in flame retardants, semiconductors and certain battery chemistries. Finding percent-level Sb with multi-gram gold can sharpen the economics if continuity holds, because co-product credits may offset mining and processing costs. For a project on private patented claims with near-mine infrastructure, that combination is worth tracking—though metallurgy, recoveries and continuity always decide the final story. 

Project setting and history: a proven gold camp

White Caps spans ~1,012 hectares across 28 patented and 74 unpatented claims, situated <2km from the historic Manhattan operation and along a structural corridor that trends toward Round Mountain. The White Caps Mine historically produced ~125,000 oz at ~30 g/t Au (1905–1964), and the company notes a 10m crosscut assaying 94 g/t Au on the lowest level that has never been followed up—a tantalising data point for deeper drilling. 

Management’s view: “reward for first-principles exploration”

Managing Director Mark Wallace framed the results as a validation of the rebuilt geological model:

“Today’s results are the reward for effort of rebuilding the geological model from the ground up via first principals’ exploration. White Caps shares similar DNA to our Golconda Project in Arizona, being a significant historical producing mine with distract scale exploration upside on patented claims close to near mine infrastructure and support.”

“Soil and rock chip sampling by G50 has uncovered a significant gold and antimony anomaly across the 2km strike of our exploration focus. This exciting discovery has been further validated by our drilling efforts, which have intercepted substantial amounts of gold and antimony, reigniting our enthusiasm for this project.

“This achievement highlights the incredible potential of applying modern technology and advanced processes to a historical mine, promising substantial exploration upside for all G50 shareholders. We can’t wait to fast-track the next round of exploration drilling to build on these promising results.” 

A quick look under the hood: what the data implies

• Continuity vs. grade: The program mixed broad lower-grade halos with short high-grade hits. That pattern is consistent with structurally focused replacement in reactive carbonate units. It suggests follow-ups should tighten spacing across fault intersections and limestone horizons where grades spike. 
• Assays and QA/QC: Some antimony results in WCRC25-007 exceeded the ICP upper limit and were re-assayed using an alternative method (Sb-AA08), a standard approach at percent-level Sb. True widths are not yet known—the company reports down-hole lengths—so geometry remains a near-term focus. 
• Targeting logic: The most prospective zones coincide with NW-trending Reliance Fault intersections and NE feeders cutting Cambrian limestone—a set-up that aligns neatly with the camp’s known deposits. UAV magnetics and geochemistry back up those lines. 
  
   

What’s next: a 2,000m core program and broader surface work

G50 plans to fast-track ~2,000m of core drilling to extend mineralisation northwest and southeast along the main structural corridor and to test newly defined high-priority targets. Expect expanded geochemical coverage, more detailed structural mapping, and additional geophysics to refine plunge and thickness on the best zones. For investors, the cadence of assay updates, step-out success and any early metallurgical insights will be the key catalysts through the December quarter. 

Key Takeaways: 

• The good: Early drilling supports the model in a prolific district, including a headline 3.5% Sb interval with multi-gram gold and several shallow gold hits. The project sits on patented ground near existing mining infrastructure—often a plus for timelines. 
• The watch-outs: True widths are unknown, continuity needs to be proven with tighter drilling, and economics hinge on metallurgy (for both gold and antimony). As always with small caps, day-to-day prices can swing on news flow. 
• The set-up: With shares at $0.36 and a $72m market cap, the next round of drilling—especially around fault intersections and that historic 94 g/t crosscut—will likely set the tone for 2026 work programs.
