500,000 tonnes of contained copper, what it's worth14 Aug 2025 08:17
From chatGPT
using your “**500,000 tonnes of contained copper**” figure, here’s a clean, order-of-magnitude view of what that could translate to in **GBP**.
### 1) Pick a reasonable copper price (USD/tonne)
Recent spot references put copper around **\$9,500–\$10,000 per tonne** (early/mid-August 2025). I’ll use **\$9,700/t** as a mid case. ([Trading Economics][1], [MacroMicro][2], [YCharts][3])
### 2) Convert USD→GBP
With **£1 ≈ \$1.35** (so **\$1 ≈ £0.74**), mid-August 2025. ([Wise][4], [Exchange Rates][5])
### 3) Gross metal value (no losses/charges)
* **USD:** 500,000 t × **\$9,700/t** ≈ **\$4.85 billion**
* **GBP:** \$4.85b × **£0.74** ≈ **£3.59 billion**
**Range check (price \$9,500–\$10,000/t):** **\~£3.52–£3.70 billion** gross.
### 4) More realistic “payable” copper
Mines don’t receive 100% of contained metal value. You’ll lose some to **metallurgical recovery** (plant) and **payability/TC-RC** (smelter terms). A simple way to reflect this is to apply an effective realization factor to contained metal:
* Illustrative effective realization (recovery × payability)
• **80%**: **\~£2.87b**
• **85%**: **\~£3.05b**
• **90%**: **\~£3.23b**
(Industry commentary this cycle notes unusually tight/volatile TC/RC terms, which affect these realizations.) ([Fastmarkets][6], [KAPARESOLUTIONS][7])
---
## TL;DR
* **Contained copper (500,000 t)** @ **\$9,700/t** → **\~£3.59bn gross**.
* After typical recovery & payability adjustments, a **sensible revenue envelope** is roughly **£2.9–£3.2bn** over the life of the project (copper only).
* Gold credits, by-product streams, and actual TC/RC contracts would nudge this up or down.
If you want, I can also sketch **low/base/high** cases tying copper price bands (e.g., \$8,500 / \$9,700 / \$11,000 per tonne) to a couple of realistic recovery/payability combos so you’ve got a quick scenario table in GBP.
