VANCOUVER, BC, Sept. 11, 2024 /CNW/ - OceanaGold Corporation (TSX: OGC) (OTCQX: OCANF) ("OceanaGold" or the "Company") is pleased to provide results from exploration and resource conversion drilling at the Haile Gold Mine ("Haile") in the United States.
Gerard Bond, President & CEO of OceanaGold, said "Today's outstanding resource conversion and definition drill results support our goal of delineating 2 million ounces underground at Haile by the end of this year. Infill drill results at Ledbetter Phase 4 are exceptional in width and grade and inform the work evaluating whether to mine the last phase of Ledbetter from underground. Additionally, new resource conversion results announced today improve our confidence in Horseshoe mineralization at depth, and results from Horseshoe Extension have intersected new mineralization proximal to existing infrastructure."
Drill highlights include (core length):
- 82.0 m @ 35.07 g/t Au Ledbetter Phase 4 (DDH1218 – conversion)
- 4.6 m @ 398.12 g/t Au, Ledbetter Phase 4 (DDH1228 – conversion)
- 71.0 m @ 16.80 g/t Au Ledbetter Phase 4 (DDH1220 – conversion)
- 45.3 m @ 21.29 g/t Au, Ledbetter Phase 4 (DDH1226 – conversion)
- 29.0 m @ 33.11 g/t Au, Ledbetter Phase 4 (DDH1230 – conversion)
- 54.4 m @ 14.82 g/t Au, Ledbetter Phase 4 (DDH1237 – conversion)
- 42.7 m @ 15.55 g/t Au, Ledbetter Phase 4 (DDH1246 – conversion)
- 48.5 m @ 8.30 g/t Au, Ledbetter Phase 4 (DDH1232 – conversion)
- 40.5 m @ 13.30 g/t Au, Horseshoe (UGD0029 - conversion)
- 16.6 m @ 9.00 g/t Au and 8.4 m @ 5.06 g/t Au, Horseshoe (UGD0030 - conversion)
- 11.6 m @ 4.05 g/t Au, Horseshoe Extension (UGD0055 – definition)

Ledbetter Phase 4
Ledbetter Phase 4 mineralization sits within the open pit reserve (Figure 1) and is currently in the mine plan as the final Ledbetter open pit phase. With a higher-grade resource at Ledbetter Phase 4 potentially sufficient to support an underground mine with improved economics, trade-off study work is underway to confirm the future preferred mining option. To support this study work, a resource conversion drill program is underway to improve confidence and provide drill core for metallurgical testing (Figure 1). A total of 9,053 metres and 24 holes have been completed, with highlights including 82.0 m @ 35.07 g/t Au from DDH1218, 4.6 m @ 398.12 g/t Au from DDH1228, and 71.0 m @ 16.80 g/t Au from DDH1220. These drill results have exceeded expectations compared to previous drilling outcomes.
An additional ~2,850 metres and 5 holes are being drilled in the remaining months of 2024 to test mineralization, approximately 50 to 250 metres to the northwest of the current Ledbetter Phase 4 resource (Figure 1).
Horseshoe and Horseshoe Extension (HEX)
Resource conversion and definition drilling undertaken from the Horseshoe Underground mine continues with 6,956 metres completed of a planned 10,605 metres this year. The results from 15 new drill holes have been received, with 3 holes supporting resource conversion of Inferred resources and 12 holes supporting resource definition of the HEX target. HEX is not currently a resource, however drilling is ongoing to test its potential as it is adjacent to the current Horseshoe Underground mine and within 150 metres of the planned decline to access Palomino Underground.
The latest drilling of Horseshoe has targeted Inferred resources in the lower zone with 3 holes all intersecting mineralization and delivering results in line with expectations based on the resource model. Highlights from Horseshoe include 40.5 m @ 13.30 g/t Au including 9.7 m @ 46.79 g/t Au (UGD0029) and 16.6 m @ 9.00 g/t Au (UGD0030) and 21.1 m @ 2.74 g/t Au (UGD0027).
Following the significant drill results reported in our April 3, 2024 press release, the latest drilling at HEX has targeted 3 zones of mineralization: upper, middle, and lower HEX. Drilling has (i) further defined continuity in the upper zone with 3 holes (UGD0046, 52, 54), (ii) defined continuity of the middle zone with 4 holes (UGD0053, 55, 56, 57), and (iii) stepped out on the lower mineralized zone to test extensions with 5 holes (UGD0037, 48, 49, 50, 51). Significantly, hole UGD0050 has intercepted mineralization of 24.2 m @ 2.47 g/t Au ~30 metres below the currently defined lower zone of mineralization (Figure 2). In addition, significant results were returned from UGD0046 with 13.7 m @ 3.42 g/t Au in the upper zone, and from UGD0055 with 11.6 m @ 4.05 g/t and UGD0056 with 27.2 m @ 1.45 g/t Au from the middle zone.
Drilling is ongoing at HEX for the remainder of 2024 with the goal to define an initial resource estimate in Q1 2025.

About OceanaGold
OceanaGold is a growing intermediate gold and copper producer committed to safely and responsibly maximizing the generation of Free Cash Flow from our operations and delivering strong returns for our shareholders. We have a portfolio of four operating mines: the Haile Gold Mine in the United States of America; Didipio Mine in the Philippines; and the Macraes and Waihi operations in New Zealand.
Qualified Person Statement
The scientific and technical information contained in this press release has been reviewed and approved by Craig Feebrey, a Member of the Australasian Institute of Mining and Metallurgy and a qualified person under National Instrument 43-101 – Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101"). Mr. Feebrey is the Executive Vice President and Chief Exploration Officer of OceanaGold.
QA/QC at Haile Gold Mine
From July 2017 to 2022 almost all Haile exploration core samples have been prepared at the ALS lab in Tucson, Arizona, and analyzed at the ALS lab in Reno, Nevada, each of which is independent from OceanaGold. Select resource conversion core samples were also prepared and analyzed at the SGS lab in Kershaw, South Carolina, which is also independent from OceanaGold, with confirmation pulp duplicates sent to ALS lab in Reno, Nevada. Samples are pulverized from a 250g (ALS) or 450g (SGS) sample to 85% passing 75 mesh. Approximately 225g of pulp sample is used for fire assay. Assays are based on a 30g fire assay aliquot for gold with Atomic Absorption finish. If the gold value from Atomic Absorption is >10g/t, an additional 30g of pulp sample is fire assayed for gold using a gravimetric finish. Some holes are composited and analyzed for carbon, sulphur and multi-elements using LECO and ICP-OES methods. Both ALS and SGS labs used for Haile OceanaGold samples are ISO 17025 certified. In 2023, select resource conversion core samples were prepared and analyzed at the SGS lab in Kershaw, South Carolina, with confirmation pulp duplicates sent to ALS lab in Reno, Nevada.
Blanks and standards are each inserted every 20th sample.. Precision and accuracy of certified reference materials ("CRMs") compared to expected values have been consistently within 5% RSD and often within 3%. Barren marble and sand are inserted as blanks every 20th sample. CRMs from RockLabs are inserted every 20th sample (5%). CRMs from RockLabs and OREAS are inserted every 20th sample (5%). All blanks and CRMs are handled by the Geology Team and are stored in the locked OceanaGold office.
All drill hole samples are handled and transported from the drill rigs to the secured Haile Exploration warehouse by OceanaGold personnel. Access to the property is controlled by locked doors and cameras monitored by OceanaGold security. The main gate requires an electronic employee badge to enter. Samples are packaged at the Haile Exploration warehouse by OceanaGold geologists and geotechnicians. Samples are trucked in sealed plastic barrels by certified couriers with submittal forms that are verified during sample pick-up and delivery to ALS. No sample shipments have been recorded as missing or tampered with.
