"Massive $1.9-Billion Didipio Mine Extension Sparks “Greenwashing” Debate in Northern Luzon" 19 July 2026

[...]

During a high-level meeting in Vancouver, Canada, President Ferdinand Marcos Jr. and top executives from the Canadian firm OceanaGold Corporation finalized a 1.9-billion US dollar investment. The new capital officially extends operations at the controversial Didipio Gold-Copper Mine by more than a decade, pushing its closure date from 2035 to the year 2037.

[...] indigenous rights groups and environmental networks are raising alarms. They accuse the state and the mining firm of “greenwashing”—a practice where a company uses public relations and environmental buzzwords to make itself look eco-friendly, while actually hiding permanent ecological damage to ancestral lands.

The Didipio Mine, nestled in the upland town of Kasibu, sits directly on the border of Nueva Vizcaya and Quirino provinces. Since launching commercial operations in 2013, it has been a massive physical operation. It started as a giant open-pit mine (a deep, open bowl carved into the earth) before transitioning into an underground operation in 2018.

The Anti-Mining Side: Upland communities and indigenous rights networks argue that the mine fundamentally alters the local environment. Critics stress that heavy extraction risks drying up and contaminating fresh water tables, triggers hazardous landslides on steep mountain slopes, and directly threatens the agricultural livelihoods of farming villages.

Why the Extended Mine Matters to the Cordillera and Sagada

While the Didipio Mine is physically located in Nueva Vizcaya, this massive extension has sent shockwaves through the neighboring Cordillera Administrative Region (CAR) and historical eco-tourism towns like Sagada.

For mountain communities in these adjacent provinces, the Didipio deal is more than just a neighbor’s business transaction—it is a direct cultural and environmental concern for three major reasons:

1. Shared Waterways: Nature does not respect regional borders. The mountains of Nueva Vizcaya and the Cordillera are connected by the same river networks and underground water sources. If mining in Didipio heavily draws from or accidentally contaminates these water tables, the effects can ripple down to the rivers that sustain farming, fishing, and daily life in nearby Cordillera communities.
2. A Threat to Indigenous Identity: In places like Sagada, the land is viewed as a sacred ancestral domain—passed down by ancestors to be protected, not bought or sold. [...]
3. The Eco-Tourism vs. Extraction Battle: Towns like Sagada have spent generations building sustainable livelihoods based on eco-tourism (traveling responsibly to natural areas to appreciate nature) and farming. They view the expanding industrial footprint of large-scale mining as the absolute opposite of their way of life. For them, a mine extension in a neighboring province increases the pressure on the entire northern mountain region, threatening to turn pristine ecological sanctuaries into industrial zones.

At the heart of the current media pushback is the charge of greenwashing. OceanaGold executives firmly deny these claims, stating that the extended 2037 timeline will rely on world-class technology designed to minimize the mine’s overall environmental footprint. The company highlights its adherence to national waste-handling standards, modern water recycling systems, and ongoing rehabilitation plans to replant trees and vegetation over disturbed land.

Conversely, regional watchdogs like the Nagkakaisang Novo Vizcayano para sa Kalikasan (United Novo Vizcayanos for Nature) point out that large-scale mining cannot coexist with true environmental preservation. They emphasize that processing thousands of tons of rock stockpiles inevitably requires massive amounts of water and chemicals, posing a continuous, long-term threat to the regional watershed.

The Presidential Communications Office confirms that both government regulatory teams and corporate engineers will spend the coming months coordinating on permitting, environmental monitoring, and community development plans.
