MONTREAL, Dec. 06, 2023 (GLOBE NEWSWIRE) -- Osisko Development Corp. (NYSE: ODV, TSXV: ODV) ("Osisko Development" or the "Company") is pleased to announce the commencement of an initial surface diamond drilling exploration campaign to test for copper-gold-molybdenum porphyry mineralization potential, at the Company’s Big Hill target area (Figure 2), at its 100% owned Tintic Project ("Tintic" or the "Tintic Project"), located in the historic East Tintic Mining District in central Utah, U.S.A. Following receipt of the required surface drill permits, the Company mobilized a diamond drill rig from Major Drilling America of Salt Lake City, Utah, which arrived at site on December 1, 2023, and commenced drilling activities (Figure 1).
Sean Roosen, Chairman and CEO of Osisko Development, commented, "With the surface drill permits in hand, we are very excited to start drilling high-priority targets on the Tintic property for copper-gold porphyry potential at depth. There was previously no detailed work completed using modern exploration techniques in these areas and we expect the initial holes to provide us with invaluable information to support our understanding and interpretation of the entire Tintic district and its potential to host a copper-gold porphyry center."
PORPHYRY TARGET DRILLING
- The Tintic District, located 65 kilometers (40 miles) from Rio Tinto's Bingham Canyon Mine, has historically been recognized as an area prospective for porphyry style copper-gold-molybdenum mineralization. Styles of mineralization and alteration present within the Tintic District support an interpretation of a classic porphyry-epithermal system with a high degree of rheologic and structural control on mineralization style and distribution (Figure 3).
- Two large lithocaps, presented as anomalous surface geochemical footprints – a type of high heat signature indicative of potential significant subsurface volcanic activity – have been identified within the Company's Tintic Project property, namely in the Big Hill and Silver Pass areas (Figure 2).
- An initial 3,000 meter (9,842 feet) of drilling in two holes comprises phase one of the surface diamond drilling program.
- The objective of this surface drilling program is to test priority targets for a potential porphyry style copper-gold-molybdenum mineral system responsible for the significant high-grade gold and silver epithermal mineralization and past producing carbonate silver-lead-zinc replacement deposits on the Tintic property.
- Recall, as noted in the Company's news release issued on October 11, 2023, drilling of the Trixie West (Figure 2) high-priority potential copper-gold-molybdenum porphyry target commenced in early October 2023 from underground at the Trixie test mine ("Trixie"). Approximately 70% of the target drill hole has been completed to date and is nearing the projected target zone (Figure 4).
REGIONAL EXPLORATION POTENTIAL
The Tintic Project is located within the historic Tintic mining district, a cluster of base and precious metal deposits covering greater than 200 square kilometres (~80 square miles) within the East Tintic Mountains of north-central Utah. Commonly divided into Main, East, North, and Southwest subdistricts, the greater Tintic District is collectively the second largest metal producing district in Utah following Bingham (Krahulec and Briggs, 2006).
Significant exploration potential exists for additional high sulphidation Au-Ag systems similar to Trixie, additional "fissure zones" adjacent to historic mines such as North Lily and Eureka Standard, historic Carbonate Replacement Deposits including Burgin, North Lily and Tintic Standard, and deep copper-gold-molybdenum porphyry targets associated with known lithocaps such as Big Hill, Silver Pass and Government Canyon, which have been scarcely explored by previous operators (Figure 2).

ABOUT OSISKO DEVELOPMENT CORP.
Osisko Development Corp. is a premier North American gold development company focused on high-quality past-producing properties located in mining friendly jurisdictions with district scale potential. The Company's objective is to become an intermediate gold producer by advancing its 100%-owned Cariboo Gold Project, located in central B.C., Canada, the Tintic Project in the historic East Tintic mining district in Utah, U.S.A., and the San Antonio Gold Project in Sonora, Mexico. In addition to considerable brownfield exploration potential of these properties, that benefit from significant historical mining data, existing infrastructure and access to skilled labour, the Company's project pipeline is complemented by other prospective exploration properties. The Company's strategy is to develop attractive, long-life, socially and environmentally sustainable mining assets, while minimizing exposure to development risk and growing mineral resources.
