The Siana Gold Project of Greenstone Resources Corp. (GRC), a wholly owned subsidiary of TVI Resource Development (Phils.) Inc. (TVIRD), received positive assessments during a recent quarterly environmental inspection that highlighted the company's renewable energy investments, rehabilitation efforts, and compliance with environmental standards.
The inspection, conducted from May 25 to 28, brought together representatives from the Department of Environment and Natural Resources-Mines and Geosciences Bureau (DENR-MGB), host barangays, and various government agencies to evaluate the project's environmental performance and sustainability programs during the first quarter of 2026.
Among the key developments reviewed was the newly completed Greenstone Solar Farm, a 5.3-megawatt-peak renewable energy facility designed to support the power requirements of the Siana processing plant.
The solar facility, which became fully operational during the first quarter, is expected to reduce carbon dioxide emissions by about 4,100 metric tons annually, an environmental benefit comparable to planting nearly 190,000 trees.
The company said the project represents the TVIRD Group's first renewable energy venture and is currently the only solar power facility in the region owned and operated by a mining company.
The multipartite monitoring team also assessed the company's progressive rehabilitation initiatives, which are being implemented alongside active mining operations.
Greenstone Chief Pollution Control Officer Alexis Jareol said environmental stewardship remains a core component of the company's daily operations.
"We uphold environmental protection every day through continuous monitoring, pollution prevention measures, and progressive rehabilitation initiatives. We strive to ensure that we operate in harmony with the environment," Jareol said.
The company emphasized that rehabilitation activities are carried out in mined-out areas while mining operations continue elsewhere on site, reflecting what it described as a proactive approach to environmental management.
Discussions during the inspection also focused on stakeholder engagement and transparency in monitoring environmental commitments.
Greenstone Tenement Management and Compliance Superintendent Erthelgin Joy Jarabe said the inspections provide an important platform for collaboration among regulators, communities, and the company.
"These engagements reinforce the importance of maintaining open communication with our regulators, host communities, and partner agencies to ensure that environmental commitments are effectively implemented," Jarabe said.
She added that the collaborative approach helps ensure environmental programs remain both effective and inclusive.
The multipartite monitoring process is part of the government's oversight mechanism for mining operations, allowing regulators and community representatives to verify compliance with environmental regulations and assess rehabilitation efforts on the ground.
Greenstone said the inspection underscored its commitment to balancing operational objectives with environmental protection and community development.
The company added that its sustainability programs are focused not only on regulatory compliance but also on ecosystem restoration, responsible resource development, and building long-term partnerships with host communities.
The Siana Gold Project is located in Surigao del Norte, one of the country's key mineral-producing provinces, where mining companies are increasingly adopting sustainability measures alongside production activities.
