Minestarters Atlas analysis

Summary

Excellon Drilling has confirmed high-grade silver-lead-zinc mineralization at its Mallay Silver Mine in Peru, with results from 15 holes showing grade and width continuity below the 4090 Level. Notable intercepts include 3.40 m at 495 g/t AgEq and 0.85 m at 600 g/t AgEq. The program also identified wide mineralized zones outside the current resource, indicating potential for significant resource growth and supporting future mine development.

Reasoning: The drill results confirm high-grade silver-lead-zinc mineralization with good width continuity below the current mining level, and identify new mineralized zones outside the existing resource, indicating strong potential for resource growth and supporting future mine development. The disclosed QA/QC procedures add confidence to the results. However, the lack of a formal economic study introduces risk.

Positive factors

  • High-grade silver equivalent intercepts, particularly MLL26-010 (495 g/t AgEq over 3.4m) and MLL26-006 (600 g/t AgEq over 0.85m), indicate strong mineralization.
  • Confirmation of grade and width continuity below the 4090 Level supports deeper mine development and resource expansion.
  • Identification of wide mineralized zones (calc-silicate system) outside the current resource estimate suggests potential for significant resource growth.
  • The drill program is designed to inform near-term mine planning and transition to more productive, mechanized mining methods.
  • QA/QC procedures are disclosed, including QP sign-off, use of ALS Global, and insertion of blanks, standards, and duplicates.

Negative factors

  • True widths are generally approximated at 80% of core length, indicating that reported intercept lengths may slightly overstate true thickness.
  • The company has not completed a preliminary economic assessment, pre-feasibility study or feasibility study, and has not demonstrated economic viability of a restart of mining operations, increasing technical and economic risks.

Low confidence — this extraction should be reviewed alongside the original source.

Facts used in scoring: 256

Classification and evidence

Bonanza Interceptpositive

Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: MLL26-006 returned 600 g/t AgEq over 0.85m, which is an exceptionally high-grade zone for silver.

Evidence · table

“600”

Context: 0.85

Bonanza Interceptpositive

Exceptionally high-grade zone, well above the deposit-type norm.

Why it applies: MLL26-010 returned 495 g/t AgEq over 3.4m, which is an exceptionally high-grade zone for silver.

Evidence · table

“495”

Context: 3.4

QA/QC Disclosedpositive

Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).

Why it applies: The technical information has been reviewed and approved by a Qualified Person, and samples are analyzed by ALS Global with insertion of blanks, duplicates, and standards.

Evidence · text

“The technical information herein has been reviewed and approved by William McGuinty (P. Geo.), a Qualified Person as defined by National Instrument 43-101. ... Samples are sent to, and analyzed, in Lima, Peru by ALS Global using their AA-Au24 and Me-ICP61b methods. ... A blank, duplicate or mineral standard is inserted into the sample stream at a rate of 1 in every 10 samples to be submitted.”

Metal Equivalent Opaquenegative

Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent.

Why it applies: Metal equivalent grade is reported without disclosing metallurgical recoveries, which are critical for accurate economic assessment.

Evidence · text

“Silver-equivalent (AgEq) is calculated with prices used in the February 2026 Mallay Mineral Resource Estimate (US$30/oz Ag, US$1.00/lb Pb and US$1.35/lb Zn). Gold is not included and metallurgical recoveries are not applied.”

Apparent Width Onlynegative

Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.

Why it applies: Intervals are reported as drill core lengths, and true widths are generally approximated at 80% of core length, indicating that reported lengths may overstate true thickness.

Evidence · text

“All intervals are reported as drill core lengths. True widths vary as holes are drilled in fans from underground drill chambers but generally approximate 80% of core length.”

Step-Out Extensionpositive

Mineralization extended beyond the previously known limit.

Why it applies: The drill program includes testing high-priority step-out targets and extending mineralization beyond previously known limits.

Evidence · text

“The Company has drilled approximately 9,000 metres to-date and has transitioned to drilling high-priority step-out targets for which assays are pending or which will be reported separately.”

Reasoning: Expanded from assay table. 138 g/t silver is moderate against the default band [500, 200, 100, 30] g/t. Grade×width 552.0 g/t·m is weak (grade alone is moderate; the better of the two is used).

Negative factors

  • Scored from rubric bands during table expansion, not from document context.

Reasoning: Expanded from assay table. 0.33 g/t gold is below against the underground mining band [15, 7, 4, 2.5] g/t. Grade×width 0.5 g/t·m is below.

Negative factors

  • 0.33 g/t gold is below the weak threshold (2.5 g/t) on the underground mining band.
  • Scored from rubric bands during table expansion, not from document context.

Reasoning: Expanded from assay table. 0.03 g/t gold is below against the underground mining band [15, 7, 4, 2.5] g/t. Grade×width 0.1 g/t·m is below.

Negative factors

  • 0.03 g/t gold is below the weak threshold (2.5 g/t) on the underground mining band.
  • Scored from rubric bands during table expansion, not from document context.

Reasoning: Expanded from assay table. 45 g/t silver is weak against the default band [500, 200, 100, 30] g/t. Grade×width 72.0 g/t·m is below (grade alone is weak; the better of the two is used).

Negative factors

  • Scored from rubric bands during table expansion, not from document context.

Reasoning: Expanded from assay table. 1.17 % zinc is below against the default band [18, 10, 5, 2] %. Grade×width 8.7 %·m is below.

Negative factors

  • 1.17 % zinc is below the weak threshold (2 %) on the default band.
  • Scored from rubric bands during table expansion, not from document context.

How Atlas produces this analysis

Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
