Oroco CEO Resigns, Casting Shadow on Key Copper Project Development

VANCOUVER, Canada – March 30, 2026 – Oroco Resource Corp. finds itself at a critical crossroads following the announcement that Chief Executive Officer Richard Lock will resign for personal reasons, effective April 30, 2026. The departure comes as the junior mining company navigates the pivotal Pre-Feasibility Study (PFS) for its flagship Santo Tomás copper project in Mexico, creating a leadership vacuum that has already unsettled investors.

In a market sensitive to executive stability, Oroco’s shares (TSX-V: OCO) slid 8.9% on the day of the announcement, reflecting investor apprehension. Lock, a mining engineer with a global track record, has been at the helm since April 2022. In the official release, he expressed gratitude for his nearly four-year tenure. “I am grateful for the opportunity to have led Oroco since April 2022 and for the dedication of the team in advancing the Santo Tomás Project and the Company's objectives,” Mr. Lock commented. “I wish the Company continued success in the years ahead.”

The board thanked Mr. Lock for his contributions and announced the formation of a committee to conduct an “aggressive search” for a successor. However, the timing of the departure injects significant uncertainty into a company whose identity is intrinsically linked to the advancement of a single, large-scale asset.

A Tenure of Growth and Challenges

Richard Lock’s leadership period was defined by a concerted push to de-risk and advance the Santo Tomás Project. He oversaw a crucial growth phase that culminated in the publication of an updated Mineral Resource Estimate (MRE) and a Preliminary Economic Assessment (PEA) in August 2024. These milestones were fundamental in demonstrating the project's potential scale and economic viability to the market.

Under his guidance, the company also engaged specialized consultants for mine-plan optimization and began navigating the complex Mexican regulatory environment by retaining an environmental law firm. These steps were seen as professionalizing the project's development path. However, this progress was set against a backdrop of financial challenges common to pre-revenue junior miners. The company has been operating unprofitably, and reports from early 2026 flagged new risks related to its financial position and share price stability, highlighting the immense pressure on its leadership.

Analyst sentiment reflects this cautious reality. Following the news, one analyst maintained a “Sell” rating on the stock, while AI-driven analysis from TipRanks assigned a “Neutral” score, citing the company's ongoing losses, negative cash flow, and the near-term leadership transition risk.

Project Resilience and Team Stability

Despite the leadership shakeup at the very top, Oroco management has moved quickly to reassure stakeholders that the work on the ground remains on track. The company stated that the Pre-Feasibility Study will proceed without interruption, guided by the Board of Directors, senior management, and its on-site technical teams.

This message of continuity is bolstered by the stability of the wider leadership group. Executive Chairman Craig Dalziel, President Ian Graham, and a management team with an average tenure of six years provide a foundation of experience. The board also includes members like Faysal Rodriguez, who brings deep local knowledge from the Santo Tomás community. This existing brain trust is now tasked with steering the project through its next technical and regulatory hurdles.

Momentum for the Santo Tomás project itself appears intact. Oroco has previously announced a planned US$20 million investment for the second phase of mineral exploration in 2025 and is actively pursuing an application to expand the scope of its mine plan. This work is critical for optimizing the project’s value ahead of a potential construction decision. The resilience of this underlying asset and the capability of the remaining technical team are now Oroco's most important selling points as it seeks to calm market nerves.

The Search for a New Vision

The search for Richard Lock's replacement is more than a routine executive hunt; it is a search for a leader who can carry a multi-billion-dollar project concept across the finish line. The board’s description of an “aggressive search” underscores the urgency of filling the role with a candidate who can immediately command investor confidence.

Given the Santo Tomás project’s advanced stage, the ideal CEO profile will likely be a seasoned mining executive with a strong background in project development and operational execution, particularly with large-scale copper porphyry deposits. Experience in securing project financing in the hundreds of millions, if not billions, will be paramount. Furthermore, a deep understanding of navigating the political, social, and regulatory landscapes of Mexico is non-negotiable for success.

The new leader will inherit a project with significant defined resources and a clear path forward but will also face the immense challenge of transitioning a junior explorer into a mine developer and, eventually, a producer. Their ability to articulate a compelling long-term strategy, secure partnerships, and maintain a steady hand through the volatile cycles of the resource market will determine whether Oroco can realize the full potential of Santo Tomás.
