Company Description
Oroco Resource Corp. (OTCQB: ORRCF; TSX-V: OCO) is a resource company focused on the exploration and advancement of the Santo Tomás copper project in northwestern Mexico. While classified under gold ore mining and the broader mining, quarrying, and oil and gas extraction sector, the company’s disclosed activities center on a large porphyry copper system and related mineral concessions.
According to company disclosures, Oroco holds a net interest in a district-scale land package at Santo Tomás. The company reports a net interest in central mineral concessions referred to as the “Core Concessions” and additional surrounding concessions that together form the Santo Tomás Project. These concessions cover several thousand hectares and are located within the Santo Tomás District, which extends toward the Jinchuan Group’s Bahuerachi Project, approximately 14 km to the northeast.
Core focus: Santo Tomás copper project
Oroco describes the Santo Tomás Project as hosting significant copper porphyry mineralization. This mineralization was initially defined by exploration programs carried out between 1968 and 1994, during which the project area was tested by over 100 diamond and reverse circulation drill holes totaling approximately 30,000 meters. Building on this historical work, Oroco commenced a Phase 1 drill program in 2021, ultimately reporting 48,481 meters of drilling in 76 diamond drill holes.
The company states that the drilling, resource estimates, and engineering studies at Santo Tomás led to a revised Mineral Resource Estimate (MRE) and an updated Preliminary Economic Assessment (PEA), which were published and filed in August 2024. These technical studies are referenced as key documents for understanding the project’s geology and potential development scenarios.
Project location and infrastructure
Oroco highlights the Santo Tomás Project’s location within approximately 170 km of the Pacific deep-water port at Topolobampo. Company materials note that the project area is connected via highway and proximal rail corridors that also carry trunk grid power lines and natural gas infrastructure through the city of Los Mochis to the northern city of Choix. Access to the property is described as being partly via a 32 km access road originally built to service Goldcorp’s El Sauzal mine in Chihuahua State.
This combination of mineral endowment and proximity to transportation and utility corridors is presented by the company as a structural characteristic of the Santo Tomás Project, rather than a short-term operational detail.
Ownership interests and project scale
In its public communications, Oroco reports that it holds a net interest in the central Santo Tomás concessions (the Core Concessions) and an 80% interest in additional mineral concessions surrounding and adjacent to those core areas. Across the various disclosures, the company describes total project areas measured in thousands of hectares and tens of thousands of acres, with the precise figures reflecting updates to concession boundaries and applications to reduce certain non-core concession areas.
These interests position Oroco as the company advancing the Santo Tomás copper porphyry system and related district-scale exploration opportunities within its concession package.
Exploration history and technical work
The company emphasizes the long exploration history at Santo Tomás and the subsequent technical work undertaken under Oroco’s stewardship. Key elements described in its releases include:
- Historical exploration from 1968 to 1994, with more than 100 diamond and reverse circulation drill holes totaling about 30,000 meters.
- A Phase 1 drill program initiated by Oroco in 2021, resulting in 48,481 meters drilled in 76 diamond drill holes.
- Resource estimation and engineering studies that culminated in a revised MRE and an updated PEA filed in August 2024.
These technical milestones are presented as the foundation for ongoing study and evaluation work at Santo Tomás.
Strategic studies and planning
Oroco has disclosed that it engaged Whittle Consulting Ltd. to perform a Strategic Option Study for the Santo Tomás porphyry copper project. The purpose of this study, as described by the company, is to optimize the mine plan and guide pre-feasibility work by examining operating strategies and project configurations. The study is expected to use Oroco’s existing project database and the Mineral Resource Estimate from the 2024 PEA.
The company’s description of this work references areas such as mine planning and optimization of project parameters, with the stated goal of providing guidance for future technical studies at Santo Tomás.
Additional district exposure: Vainilla concession
Through its wholly owned Mexican subsidiary Minera Xochipala, S.A. de C.V., Oroco has entered into an option agreement to acquire a 100% interest in the Vainilla Mineral Concession in the Choix District of northern Sinaloa, Mexico. The company states that this concession covers approximately 2,974 hectares within a porphyry copper belt anchored by the Santo Tomás Project.
Oroco’s public description of the Vainilla Concession notes the presence or proximity of multiple zones of historical and active polymetallic mineralization, including skarns, breccia pipes, and vein systems that are interpreted as related to monzonite intrusions. The company characterizes this concession as offering exploration opportunities for copper and associated metals and as complementary to Santo Tomás in a geological and potential economic sense.
Regulatory and permitting developments
The company has reported a positive resolution from Mexico’s federal environmental authority, SEMARNAT, in response to its “informe preventivo” notice of exploration activities on the Santo Tomás Project. Oroco states that SEMARNAT’s resolution indicates that the planned drilling and exploration activities described in the notice do not require a separate Environmental Impact Authorization, allowing those activities to proceed in accordance with the characteristics set out in the notice.
Oroco has also referenced the inclusion of the Santo Tomás Project in regional development initiatives such as Plan Sinaloa and Plan Mexico in the context of its communications about government and community support. These references appear in the company’s own commentary on the broader setting for the project.
Capital markets and financing activity
Oroco’s shares trade on the TSX Venture Exchange under the symbol OCO and on the OTCQB market under the symbol ORRCF. The company has described several financing activities in its public news releases, including non-brokered private placements and a bought deal public offering of units consisting of common shares and common share purchase warrants. These offerings are presented as being used to fund technical work, drilling, and corporate purposes related to the advancement of Santo Tomás and associated studies.
In connection with these financings, Oroco has outlined the structure of units, warrant terms, and commissions paid to underwriters, as well as the filing of a base shelf prospectus and prospectus supplements in Canadian jurisdictions outside Québec. The company has also described offerings made to qualified institutional buyers in the United States under exemptions from registration.
Corporate governance and leadership
Oroco’s disclosures reference a board of directors and senior leadership team with experience in mining and project development. For example, the company has announced the appointment of a director with extensive experience in mine development and operations in Mexico and other jurisdictions, highlighting that individual’s background in mine management, operations, government relations, and community engagement.
The company has also organized shareholder engagement initiatives, such as virtual town halls featuring its executive chairman and president, to provide updates on management, permitting, community engagement, and next steps in advancing Santo Tomás.
Project context and development stage
Across its public communications, Oroco consistently describes itself as advancing the Santo Tomás copper project through technical studies and exploration. The project is characterized as a large-tonnage, open-pit copper porphyry deposit located near established infrastructure corridors and within a recognized mining district. The company refers to the PEA and subsequent work as the basis for further evaluation and planning activities.
Oroco’s statements also note that the company intends to continue technical and strategic work at Santo Tomás, including drilling and studies that build on the existing resource and engineering information. These descriptions position Oroco as a resource company focused on the exploration and evaluation phase of a copper porphyry project, with additional district-scale exploration exposure through the Vainilla Concession option.
