OROCO COMMENCES PHASE 2 DRILLING

MWN-AI** Summary

Oroco Resource Corp. (TSX-V: OCO, OTCQB: ORRCF) announced the initiation of Phase 2 drilling at its Santo Tomás copper project in northwestern Mexico, following recent financing by Canaccord Genuity. The company has mobilized a diamond drill rig to the project's South Zone, marking a significant advancement in their on-site work program. This phase will focus on infill and confirmation drilling, aimed at enhancing the geological and grade model in areas where increased drilling density can improve resource confidence for future mine planning and engineering.

Complementing the drilling activities, Oroco will simultaneously conduct Pre-Feasibility Study (PFS) programs to advance project engineering and mitigate technical risks. These studies will encompass hydrogeological assessments—collecting baseline water data and testing for effective water management, along with geotechnical logging and testing necessary for appropriate pit slope and infrastructure design. Additionally, metallurgical programs will involve collecting samples for testing to ensure processed material meets PFS standards.

Oroco's Chairman, Craig Dalziel, emphasized the project’s potential benefits for both shareholders and the local community, noting the strong support from regional government and residents. The Santo Tomás project encompasses a land area of 1,173 hectares with a significant history of porphyry copper mineralization defined by previous exploration efforts from 1968 to 1994. Oroco's ongoing commitment to the Santo Tomás project, including a Phase 1 drill program completed in 2021, showcases their strategic focus on developing this resource, further supported by its proximity to key transportation infrastructures like the Pacific deep-water port at Topolobampo.

MWN-AI** Analysis

Oroco Resource Corp. (TSX-V: OCO, OTCQB: ORRCF) has recently announced the commencement of Phase 2 drilling at its Santo Tomás copper project, a move that presents significant market implications for investors and stakeholders. This phase aims to enhance the mineral resource classifications in the project's South Zone, a crucial step that could bolster the project’s credibility and economic viability, ultimately driving shareholder value.

The mobilization of a diamond drill rig signifies a tangible shift towards advancing the project, following a successful financing round led by Canaccord Genuity. Initial drilling efforts will focus on infill and confirmation operations, which are expected to refine the geological model—an important factor for improving confidence in future mine planning. As the drilling progresses, there’s potential for increased resource estimation accuracy, which can positively influence market perception and stock performance.

Simultaneously, Oroco is conducting complementary Pre-Feasibility Study (PFS) programs that incorporate hydrogeological, geotechnical, and metallurgical assessments. These studies are essential to mitigate technical risks and enhance the project’s feasibility, making it more attractive to potential investors and strategic partners. The emphasis on comprehensive data collection reinforces Oroco's commitment to due diligence and responsible resource management.

Given the strategic location of the Santo Tomás Project within proximity to infrastructure such as deep-water ports and highways, the operational logistics enhance the overall attractiveness of the investment. The local community's support, as highlighted by Oroco's Chairman, further underscores the social license essential for mining operations.

For investors, this is an opportune moment to consider building positions in Oroco Resource Corp., given the potential for significant upside tied to successful drilling results and further resource upgrades. Monitoring the results from the ongoing Phase 2 drilling and the outcomes of the PFS will be critical in evaluating future investment risks and opportunities.

VANCOUVER, Canada, Feb. 24, 2026 (GLOBE NEWSWIRE) -- Oroco Resource Corp. (TSX-V: OCO, OTCQB: ORRCF) (the “Company” or “Oroco”) is pleased to announce that it has mobilized a diamond drill rig to its Santo Tomás copper project, located in northwestern Mexico, to commence drilling intended to support the upgrade of the mineral resource classifications in the project’s South Zone.

This mobilization represents the practical start of Oroco’s Phase 2 on-site work program following the Company’s recent financing led by Canaccord Genuity.  Initial work will prioritize both infill and confirmation drilling designed to refine the geological and grade model in areas where increased drilling density is expected to support improved confidence for future mine planning and engineering work. Additional drills will be added as required.

In parallel with the resource-classification drilling, Oroco will undertake complementary Pre-Feasibility Study (“PFS”) programs intended to advance project engineering and reduce technical risk.  Those programs will include the following work:

  • Hydrogeological, including collection of baseline and operational water data, targeted hydrogeological testing where required, and integration of results into water management planning;
  • Geotechnical, including systematic geotechnical logging of drill core, core orientation and structural data where appropriate, and the collection of parameters relevant to pit slope and infrastructure design; and
  • Metallurgical, including additional sample collection to support variability, comminution, and process-response testing to a PFS standard.

Commenting on the mobilization, Oroco’s Chairman, Craig Dalziel stated: “The mobilization to the South Zone at Santo Tomás marks the restart of a project that is not only of great value to the shareholders of Oroco but is also essential to the future of a local community that, along with the regional government, has been so supportive of the project.  We are so very thankful to be located in an area of Mexico where the potential benefits of the Santo Tomás Project are so widely appreciated.  We look forward to the many contributions, both local and federal, that the success at Santo Tomás is likely to provide.

ABOUT OROCO 

Oroco’s focus is the development of its Santo Tomás Project in northwestern Mexico. The Company holds a net 87.0% interest in the central concessions comprising 1,173 hectares (the “Core Concessions”) and an 80% interest in additional surrounding concessions. On a consolidated basis, the Santo Tomás land package has been the subject of an area rationalization process affecting one non-core concession, resulting in a reduced overall project area.

Santo Tomás hosts significant porphyry copper mineralization initially defined by extensive prior exploration (1968–1994), including over 100 diamond and reverse circulation drill holes totaling approximately 30,000 metres. Commencing in 2021, Oroco completed a Phase 1 drill program at Santo Tomás totaling 48,481 metres in 76 diamond drill holes, which supported subsequent resource estimation and engineering work, including a revised mineral resource estimate and updated PEA published and filed in August 2024.

The Santo Tomás Project is located within 170 km of the Pacific deep-water port at Topolobampo and is serviced via highway and proximal rail (along corridors of trunk grid power and natural gas) through Los Mochis to the northern city of Choix.
