Prickly
An AI update 😃
Yes — the 66 million ounces of silver number is real, but it’s important to understand what that number actually means.
The Namib Lead Zinc Mine resource statement shows:
1.12 million tonnes of ore
containing approximately
25,900 tonnes of lead
74,200 tonnes of zinc
66 million ounces of silver (in-situ) �
North River Resources +1
⚠️ The key detail: “in-situ” silver
The 66 million oz is metal in the ground, not what the mine will produce.
“In-situ” means:
➡ Theoretical metal contained in the rock before mining losses, recovery losses, and dilution.
What the mine actually produces
The feasibility studies for the project estimate annual silver production around 280,000 oz per year when operating. �
Mining Weekly
So the mine economics look more like:
~250,000 tonnes ore processed per year
~280k oz silver annually
Why the “66M oz” number looks huge
Because it counts all silver present in the ore body, not just recoverable metal.
Think of it like this:
Category
Silver
Silver in the rock (theoretical)
~66M oz
Recoverable in mine plan
much smaller
Annual production
~280k oz
The silver grade explains the number
The ore averages roughly 40–45 g/t silver. �
Mining Weekly +1
That’s actually quite a good silver grade for a lead-zinc mine.
Example comparison:
Deposit type
Silver grade
Typical base metal mine
10–20 g/t
Good polymetallic mine
30–50 g/t
Namib Lead Zinc
~40–45 g/t
So the grade itself is believable.
Interesting point for your earlier question
That ~43 g/t silver number may actually be the “42” someone misread as gold in that LSE post.
So the person probably confused:
42 g/t silver with
42 g/t gold
Which would explain the huge mistake in their calculation.
✅ Conclusion
Yes, the 66M oz silver figure is real.
But it represents total metal in the ground, not mine output.
Actual production is a few hundred thousand ounces per year.
