Iran Deal Hopes Crash Oil Past Five Percent, Copper's Q1 Surplus Tells a Different Story Than the Price, Gold Retreats From the Summit, and Mount Holland Gets Cleared to Double

In today's episode of The Mining Insider, Logan Ore covers four major developments shaping the global mining industry:

1. Iran Deal Hopes Send Oil Below $100 — President Trump says a US-Iran framework to reopen the Strait of Hormuz is largely negotiated. Brent crude falls 4.6% to $98.80/bbl, WTI drops 4.7% to $92/bbl. The Strait has been effectively closed since February 28, cutting ~20% of global oil and LNG flows and driving up diesel, sulphuric acid, and freight costs for mines worldwide. Analysts at MST Financial warn that even with a deal, markets will remain tight through 2027.

2. Copper Q1 2026 Surplus: 396,000 Tonnes — ICSG May 2026 Copper Bulletin reveals a refined surplus nearly three times the Q1 2025 figure of 135,000T. Mine disruptions: Grasberg -42%, Kamoa-Kakula -36%, Chile -5.8%. Refined production surged: China +8.8%, India +25%. The surplus is concentrated in China; Western prices remain elevated on forward demand expectations.

3. Gold Near $4,500 — Two Headwinds — Gold holds in the $4,500–$4,569 range, pulled back from the May high of $4,743. Iran ceasefire progress reduces geopolitical risk premiums. India's gold import duty raised from 6% to 15% (steepest increase on record) — World Gold Council estimates 50–60 tonne decline in Indian demand in 2026.

4. Mount Holland Lithium Mine Approved to Double — SQM and Wesfarmers' 50-50 JV in Western Australia receives approval to expand spodumene capacity to 4.4Mtpa. Spodumene prices hit $2,890/t on May 12, a 2-year high. Benchmark Mineral Intelligence warns that broader Australian supply increases could pressure prices and create a surplus by 2027.
