The National Bureau of Investigation-Rizal District Office (NBI-RIZDO) arrested six individuals in an illegal quarry operation on April 28, 2026, in Barangay San Salvador, Baras, Rizal. The raid, executed by armed NBI agents, uncovered a large-scale unauthorized excavation site lacking any permits from the Municipality of Baras.

NBI Raids Unauthorized Quarry Site

NBI-RIZDO operatives swooped down on the quarry site following months of surveillance and intelligence gathering. The operation targeted an illegal mining hub run by unknown individuals in the mountainous barangay. According to records obtained by the NBI, the Municipality of Baras has not issued any permits or documents authorizing quarry activities at the location. The suspects processed and sold river aggregates—sand, gravel, and boulders—without legal clearance.

Suspects Face Multiple Charges

The arrested individuals are Armando Oriñas, John Robert Gonzales, Erven Icalabis, Rodel Briones, Alexander Catan, and Nestor Cadavez. They are now facing charges for violation of Republic Act No. 7942, or the Philippine Mining Act of 1995, and Presidential Decree No. 1586, which mandates environmental impact assessments for such operations. The NBI said the group may also be charged with illegal possession of explosives and firearms found on-site.

Environmental and Economic Impact

Illegal quarrying in Baras poses serious threats to the environment. Unregulated excavation destabilizes riverbanks, accelerates soil erosion, and pollutes water sources. The municipality, located along the Sierra Madre mountain range, is a critical watershed area for Metro Manila and nearby provinces.

Lost Revenues for Local Government

The Municipality of Baras loses substantial revenue from uncollected taxes and fees. Legal quarry operations require permits, environmental compliance certificates, and royalty payments. The absence of these permits means the local government misses out on funds for infrastructure, education, and health services. The NBI estimates the illegal operation extracted materials worth millions of pesos.

Timeline of the Investigation

The NBI-RIZDO started monitoring the site after receiving complaints from residents. Officials from the Department of Environment and Natural Resources (DENR) and the Mines and Geosciences Bureau (MGB) confirmed the lack of valid permits. The April 28 raid was executed after NBI Director Jaime B. Santiago approved the mission order. Agents seized heavy equipment, including a backhoe and dump trucks, as evidence.

Local Residents' Reactions

Barangay San Salvador residents expressed relief but also fear of retaliation. "The trucks would come every night, and the noise was deafening," a resident who requested anonymity told the Inquirer. Many residents worried about the safety of the road leading to the quarry, which is often used by children walking to school.

Broader Crackdown on Illegal Mining in Rizal

This arrest is part of a larger push by the NBI and the DENR to crack down on illegal mining in Rizal province. In 2025, authorities dismantled similar operations in Tanay and San Mateo. The NBI warns that illegal quarrying often involves organized crime syndicates and may be linked to other illegal activities such as illegal logging and land grabbing.

Legal Framework and Penalties

Under RA 7942, illegal small-scale mining carries a penalty of six to 12 years imprisonment and a fine of up to PHP 2 million. Large-scale operations, such as the one alleged in Baras, may result in higher penalties, including rehabilitation costs. The suspects are currently detained at the NBI-RIZDO facility in Antipolo while inquest proceedings are underway.

Significance for Filipino Readers

The Baras quarry bust highlights a persistent problem in the Philippines: illegal resource extraction that harms both the environment and local economies. For Filipinos, this means cleaner rivers and safer roads, but it also underscores the need for vigilant law enforcement. As the NBI tightens its grip on illegal mining, residents hope this raid sets a precedent for protecting the Sierra Madre watershed, a natural buffer against typhoons and floods. The case also reminds local governments to enforce strict permit checks to ensure sustainable development in their towns.
