Taseko Updates Florence Copper and Gibraltar First Quarter Production
Florence Copper Production Confirmed, Gibraltar Ramp-Up Validates Guidance Amidst Cost Headwinds

Executive Summary
- Taseko Mines reported Q1 2026 production results for its two primary assets: Florence Copper and Gibraltar Mine.
- Florence Copper SX/EW plant commenced operations mid-February 2026; produced 1.5 million pounds of copper cathode in Q1.
- Initial leaching and production are aligned with modeling; focus is on balancing solution flow and grades for ramp-up.
- Four drills currently operating at Florence, fifth expected shortly to increase solution flows.
- Gibraltar Mine saw significant year-over-year growth: Copper up 50% (30.0 million pounds), Molybdenum up 113% (717 thousand pounds).
- Recoveries improved to 83%; copper grades remained in line with life of mine average grade.
- LME copper prices rose 16% over the previous quarter, supporting revenue per pound.
- Rising diesel prices estimated to increase Gibraltar operating costs by US$0.10 to US$0.15 per pound for the year.
- Fixed price contract in place for all 2026 sulphuric acid requirements at Florence, mitigating inflationary pressure on that asset.
Material Impact
- The news confirms the successful start-up of Florence Copper announced in March 2026 ("First Cathode Harvest"), validating the execution timeline without significant delays.
- Gibraltar production beat expectations with a 50% year-over-year increase, aligning with management's guidance raised in February 2026 (110–115 M lbs for full year).
- The diesel cost increase ($0.10-$0.15/lb) is a negative operational headwind but appears manageable given the production volume growth and hedging program mentioned in prior releases.
- This update is largely consistent with previous expectations set during the Q4 2025 earnings call (Feb 18, 2026) and the March milestone announcement; it does not introduce fundamentally new catalysts or surprises.
- The confirmation of production volume reduces execution risk for Florence Copper but does not alter the valuation thesis significantly as the market has already priced in the start-up success over the last quarter (price moved from ~$8 to $12 range).
- Rating is Routine - Positive because it serves as a verification of previously announced milestones rather than a new material development.
