OceanaGold Corporation (TSX: OGC | NYSE: OGC) released new high-grade drill results from its Haile Gold Mine in Lancaster County, South Carolina, showing mineralization expanding in multiple directions across three target areas.
The headline intercepts are hard to ignore. Horseshoe Underground returned 15.5 metres at 30.64 g/t gold and 30.5 metres at 13.86 g/t gold. Ledbetter Underground hit 27.9 metres at 8.60 g/t. At Clydesdale, a newer target, early drilling returned 14.5 metres at 15.81 g/t gold including 4.5 metres at 41.6 g/t. Intervals are down-hole core lengths; true widths have not been determined.
The Mine Putting These Numbers in Context
Haile is the only active gold mine east of the Mississippi River. OceanaGold listed on the New York Stock Exchange on April 7, with the company’s CEO citing Haile specifically as the catalyst. The mine accounts for 45% of the company’s total gold production, targeting 315,000 ounces in 2026, up 35% year-over-year, at an all-in sustaining cost of approximately $1,000 per ounce.
Three Targets, Three Stories
Gold is trading above $4,600 per ounce. At that price, a $1,000 AISC margin generates cash at a rate that explains OceanaGold’s Q1 2026 free cash flow of $255 million and its recently announced $240 million expansion investment with 200 new jobs at the site.
Horseshoe is the most advanced. Defined mineral reserves are already in place, and the 2026 program targets both reserve growth and extension of mineralization still open in multiple directions. Conversion holes in the lower levels are returning results in line with the resource model and are expected to feed the next reserve update. The extension holes are the more interesting story: new intercepts outside the current resource shell suggest the system is larger than what is already planned for mining.
Ledbetter converted from an open pit to underground mining plan earlier this year, a decision that opened up mineralization below the prior pit shell that is now potentially economic. Conversion drilling is confirming continuity of the high-grade zone down plunge, with several holes returning grades higher than the model predicted.
Clydesdale is the emerging target. Located 800 metres below surface and 300 metres stratigraphically below Palomino, it has now returned two significant intercepts. The second, 14.5 metres at 15.81 g/t gold, confirms the first was not a one-hole anomaly. The Palomino decline currently under development will eventually provide underground drill access to Clydesdale at shorter distances, accelerating the program once it is in place.
What the 2026 Program Is Building Toward
Approximately 34,500 metres of drilling is planned at Haile this year from both surface and underground platforms. The program is methodical: resource conversion at Horseshoe, infill and extension at Ledbetter, and early-stage definition at Clydesdale and Pisces. Three years of surface exploration work plus refined geological modelling are now generating systematic targets rather than opportunistic ones.
Inferred mineral resources referenced in this release are not mineral reserves and do not have demonstrated economic viability. Conversion from inferred to indicated, and ultimately to reserves, is the work the 2026 program is designed to advance. At current gold prices, the economics of that conversion effort are as favorable as they have ever been for Haile.
