Can Telfer Still Hold 10 Moz of Gold?
✅ What’s Already Known / Indicated:
1. Remaining Resources (2023 estimates):
Telfer still has around 2.5–3 Moz in underground and open pit reserves/resources.
This includes the A-Reefs, Main Dome, and West Dome extensions.
🟡 Where Could the Rest Come From?
2. Eastern Stockwork Corridor (ESC):
Estimated bulk-mineable zone:
1,000m × 100m × 40m = 4 million m³
Assuming density ~2.7 t/m³ → ~11 million tonnes
At 3–5 g/t, that’s 1–1.8 Moz
✳️ That's just one new zone, close to infrastructure and easily mined.
3. A50–A80 Reefs Extensions:
High-grade reefs (5–20 g/t) with long, mineable widths
These could conservatively host 1–2 Moz, and they’re being drilled now.
4. Open Pit Extensions – Stage 7 / Stage 2:
Thick intercepts, e.g. 37m @ 3.4 g/t
Near-surface additions = ~500,000–1 Moz
5. Deeper Main Dome / Below West Dome:
Telfer’s mineral system is large, folded, and open at depth.
Deeper drilling could reveal a continuation of current lodes.
Even a 300–500m extension of known systems could unlock 2–3 Moz more.
6. Undrilled Adjacent Targets:
There are large gaps beside and below the current mine with no modern drilling.
Much of Telfer’s tenure is underexplored due to:
Old tech
Low gold prices pre-2005
Focus on known ore zones
🔎 Summary of Upside Potential
Source Potential (Moz)
Existing resources/reserves ~2.5–3.0
ESC (Eastern Stockwork Corridor) ~1.0–1.8
A-Reefs extensions ~1.0–2.0
Stage 7/2 open pit extensions ~0.5–1.0
Main Dome deeper/West Dome deeper ~2.0–3.0
Undrilled nearby zones ~1.0+
Total Potential 8–11 Moz
🧠 Final Thought:
10 million ounces is aggressive, but reasonable for a world-class system like Telfer — especially over a 10–20 year life extension, if drilling continues to reveal more zones like ESC and A-Reefs.
