Is this a good drill hole results? Expansion of the Rubidium targets at Mt Edon https://cdn-api.markitdigital.com/apiman-gateway/ASX/asx-research/1.0/file/2924-03052334-6A1310238&v=undefined

Yes, the drill hole results from Everest Metals Corporation's (ASX: EMC) Phase 2 program at the Mt Edon Critical Minerals Project in Western Australia appear to be strong and positive for several reasons. I'll break it down based on the key data from the November 2025 announcement, contextualize what makes them "good" in the mining exploration space (especially for a rare critical mineral like rubidium), and compare to the project's existing resource.Key Drill Results HighlightsThe Phase 2 program involved over 2,500m of drilling (19 reverse circulation (RC) holes for 1,813m, 8 slimline RC holes for 502m in step-out areas, and 2 diamond holes for 192m focused on metallurgical and geotechnical testing). Assays were received for the initial 1,813m of RC drilling, with additional results expected in December 2025 (though as of early 2026, no major updates have been noted in public sources).

Strike Rate and Consistency: 100% of the 19 RC holes intersected pegmatite bodies (the host rock for rubidium mineralization), indicating excellent geological continuity and low exploration risk.
Peak Grade: Up to 0.79% Rb2O (rubidium oxide), which is exceptionally high for rubidium deposits.
Notable Intercepts (aggregated from standout holes; specific hole IDs weren't detailed in public summaries, but these represent the best reported):120m @ 0.22% Rb2O from surface, including a higher-grade zone of 26m @ 0.40% Rb2O from 82m.
20m @ 0.37% Rb2O from 50m.

Other Minerals: The drilling confirmed potential for additional critical minerals like lithium (Li2O) and caesium (Cs), though specific grades for these weren't quantified in the results summary. Previous drilling at Mt Edon has shown associated Li2O grades around 0.07%.
Expansion Aspects: Step-out drilling in priority areas extended the known mineralization, with pegmatites remaining open in multiple directions. This supports target expansion along the 1.2km pegmatite corridor.

These results are interim and will feed into a mineral resource estimate (MRE) upgrade targeted for Q1 2026.

Why Are These Considered Good Results?In mineral exploration, "good" drill results are evaluated based on grade, thickness, consistency, and implications for resource growth or economics—especially for niche commodities like rubidium, which is used in high-tech applications (e.g., aerospace, defense, and specialty chemicals) and has limited global supply. Rubidium deposits are rare, and Mt Edon is touted as Australia's highest-grade discovery.

Grade Quality: The average intercept grade (0.22% Rb2O) matches the project's existing maiden Inferred MRE (3.6Mt @ 0.22% Rb2O, containing ~7,900t Rb2O at a 0.10% cutoff).

However, the higher-grade zones (0.37-0.40%) and peak (0.79%) exceed the high-grade subset of the MRE (1.3Mt @ 0.33% Rb2O at a 0.25% cutoff), suggesting potential to boost overall grades in the upgrade. Economic rubidium grades typically start around 0.1-0.2% Rb2O in pegmatites, so these are well above threshold and competitive globally (e.g., compared to lepidolite-hosted deposits in China or Canada).
Thickness and Volume Potential: Thick intercepts like 120m near surface are excellent for open-pit mining viability, reducing stripping ratios and costs. The 100% hit rate and open mineralization indicate room for tonnage growth beyond the current 3.6Mt.
Expansion Impact: The step-outs confirm extensions, which could significantly expand the resource base. This de-risks the project and supports EMC's goal of building Australia's first rubidium industry, with ongoing metallurgical work showing up to 97% recovery via their proprietary Direct Rubidium Extraction (DRE) tech.

Market Context: Rubidium prices are volatile but high (~US$1,200-1,500/kg for RbCl), driven by demand growth (CAGR ~5%). Positive results like these could attract funding or partnerships, especially with EMC's patent-pending extraction tech and grants (e.g., AEA Ignite funding).

Compared to earlier Phase 1 drilling (e.g., 80m high-grade intercepts in 2024), these build on success by focusing on upgrades and extensions, with similar or better grades.

No major negatives (e.g., no barren holes or dilution issues) were reported.Potential CaveatsThese are partial results; full assays could refine the picture.
Rubidium projects are early-stage and face metallurgical/permitting hurdles, but EMC's 97% recovery rates are promising.
Market sentiment: EMC's share price reacted positively post-announcement, but volatility in small-cap miners is common.

Overall, these results are a solid win for resource expansion and project advancement. If you're investing or tracking, watch for the Q1 2026 MRE update. For more details, check EMC's ASX filings or the full announcement PDF via their investor portal.
