Q: "can you give me an estimate resource using historical drill results and recent drill results for Yarrol"

Based on the available drill data and geological parameters, here's a rough order-of-magnitude resource estimate for Yarrol. Note that this is an indicative calculation only — a proper JORC resource requires detailed geological modeling and qualified person sign-off.
Key Geological Parameters
Parameter Value Source
Confirmed strike length 500m+ (Yarrol North) Mila drilling
Total system 20km Yarrol Fault Company reports
Historic depth ~60m Historical drilling
Current depth 230m+ confirmed Mila diamond drilling
True width 10-15m estimated Based on 50-75% of reported intervals
Bulk density 2.7 t/m³ Typical hard rock
Historic resource ~100k oz @ 1.5 g/t Non-JORC, shallow
Rough Resource Estimate (Drilled Area Only)
Assumptions:
Strike: 500m (conservative — just the confirmed Yarrol North zone)
True width: 12m average
Depth: 200m (vertical)
Average grade: 1.8 g/t (blending 1.5 g/t historic with higher-grade Mila intercepts)
Calculation Value
Volume 500m × 12m × 200m = 1,200,000 m³
Tonnes 1.2M m³ × 2.7 t/m³ = ~3.2 Mt
Contained gold 3.2 Mt × 1.8 g/t = ~5,760 kg
Ounces ~185,000 oz Au
Potential Resource Range
Scenario Tonnes Grade Ounces Basis
Conservative (current drilling only) 2.5-3.5 Mt 1.5-2.0 g/t 120,000-225,000 oz 500m × 10m × 150m
Moderate (extensions to 300m depth) 5-7 Mt 1.5-2.0 g/t 240,000-450,000 oz 600m × 12m × 250m
Optimistic (1km strike, 300m depth) 10-15 Mt 1.5-2.0 g/t 480,000-960,000 oz Includes high-grade shoots
Comparison to Historic
Historic Mila Potential
Ounces ~100k oz 150k-250k oz (current drilling)
Grade 1.5 g/t 1.5-2.0+ g/t (higher-grade zones included)
Depth <80m 230m+ (3× deeper)
Strike tested <2km of 20km 500m+ confirmed, 20km potential
Bottom Line
Based on current drilling, Yarrol likely hosts 150,000–250,000 oz Au at ~1.5–2.0 g/t in the immediate Yarrol North area — roughly 2× the historic resource.
If Mila can extend the 500m zone to 1km+ strike and 300m depth with similar grades, the project could approach 400,000–500,000 oz (which aligns with their EMX agreement milestone of 400,000 oz by year 5).
The upside case (20km fault, multiple targets) could theoretically host 1M+ oz, but that requires significant additional drilling.
