CAGAYAN DE ORO CITY — Authorities have intensified their crackdown on illegal mining in Misamis Oriental after a 29-year-old man was allegedly caught processing mineral ore without the required permits in Barangay Limonda, Opol town.
The operation was carried out around 5:20 p.m. on September 2 in Zone 2 of the hinterland village, where joint police and military personnel reportedly found the suspect operating ball mill drums used in mineral processing.
Police identified the suspect only as “Gil,” a local resident of Misamis Oriental. Authorities said he failed to produce valid documents authorizing the mining-related activity and was subsequently arrested.
10 ball mill drums and 16 sacks of ore seized
The raid resulted in the confiscation of 10 ball mill drums and 16 sacks of unfinished milled ore, with the seized materials estimated at approximately P280,000.
The equipment and mineral ore were documented as part of the evidence gathered during the operation. The ore was brought to the police station for documentation and proper disposition, while the ball mill drums were placed under temporary custody pending turnover to the Mines and Geosciences Bureau (MGB).
Ball mills are commonly used to grind mineral-bearing material into finer particles for further processing, making their presence significant in investigations involving suspected unauthorized mineral processing.
Multi-agency operation targets illegal mining
The operation involved personnel from the Opol Municipal Police Station, 2nd Provincial Mobile Force Company, Regional Mobile Force Battalion 10, Philippine Army’s 88th Infantry Battalion, Task Force Opol, and MGB-deputized personnel from Task Force Kalikasan ug Kalinaw.
Police Regional Office 10 Director Brig. Gen. Nestor Babagay Jr. said the operation demonstrated authorities’ continuing efforts to prevent unlawful exploitation of natural resources in Northern Mindanao.
The suspect remains in police custody and is facing a case involving alleged violation of the Philippine Mining Act of 1995, Republic Act No. 7942. The case remains subject to legal proceedings.
Crackdown comes after repeated mining operations in Opol
The latest arrest is not an isolated incident.
Misamis Oriental authorities have been conducting repeated operations against suspected illegal mining in Opol throughout 2026.
In January, authorities arrested 24 people, including two Chinese nationals, during a raid on a suspected large-scale illegal mining operation in Barangay Tingalan, Opol. Authorities reported confiscating equipment and mineral ores valued at approximately P30.8 million.
In March, another operation in Barangay Limonda resulted in the arrest of a retired police officer and seven other individuals. Authorities said they seized mining equipment, suspected mineral ores and substances allegedly used in mineral processing.
The crackdown continued in April, when two active police officers and four civilians were arrested at a checkpoint while allegedly transporting suspected mineral ores without the required documents. Police reported recovering 58 sacks of suspected unprocessed mineral ore, estimated at around P290,000, along with firearms and ammunition from the two police officers.
Authorities had already ordered mining sites closed
The problem became even more apparent in late August.
On August 25, the Misamis Oriental provincial government, MGB and law enforcement agencies returned to mining sites in Barangay Limonda to enforce a cease-and-desist order.
Authorities said some of the sites had previously been ordered closed but reports indicated that mining activities had resumed. The operation documented 89 tunnel portals, 18 ball-mill mini plants, four generator sets, six jackhammers, six air-blower pumps, four chainsaws and 50 sacks of alleged mineral ore, among other equipment.
That development underscored a major challenge facing authorities: closing an illegal mining site does not necessarily mean the activity disappears.
Government weighs legal pathway for small-scale miners
At the same time, the provincial government has indicated that it wants to distinguish between unauthorized mining operations and small-scale miners who could potentially operate legally.
Governor Juliette Uy has pushed for the registration of eligible activities under the government’s “Minahan ng Bayan” program while maintaining the crackdown on unauthorized operations.
The strategy seeks to bring qualified small-scale mining activities into a regulated framework while preventing operations that continue without the necessary permits and environmental safeguards.
The province’s campaign has also been linked to broader environmental protection efforts, particularly in areas surrounding the Iponan watershed, where unauthorized extraction has raised concerns over land and water resources. Regional reports have previously linked illegal mining in the area to environmental degradation and risks to waterways.
The bigger question: Can authorities keep the mines closed?
The September 2 arrest shows that enforcement remains active despite previous closures and arrests.
For authorities, the challenge now extends beyond confiscating equipment and arresting individual operators. Sustained monitoring will be needed to determine whether other mining sites remain active, whether previously closed operations reopen, and whether larger networks are behind the continuing extraction of mineral resources.
The latest operation therefore represents another enforcement action in a much larger campaign—one that authorities have been pursuing across Misamis Oriental throughout the year.
And with 89 tunnel portals and numerous processing facilities previously documented in the same area, the latest arrest may be only one piece of a much larger illegal-mining problem still being investigated.
