MGB-10 files Criminal Charges against Manalo Mining Group

MGB-10 files criminal charge against Manalo Mining Group for “Theft of Minerals” under R.A. 7942, otherwise known as the Philippine Mining Act of 1995 on April 13, 2009.  The crime is punishable upon conviction by imprisonment from six (6) months to six (6) years plus fine. The Office will also confiscate all equipment, tools and conveyance used in the illegal mining activities.

Prior to the filing of the aforesaid criminal case by MGB -10, the following is the chronology of events:

Sometime in late July 2008, Pastor Semilla, representative of the Manalo Group, went to MGB-10 and informed the office that they are applying for a Small Scale Mining Permit (SSMP), however, they lack the social acceptability certification from the LGU Opol. The Manalo Group has also informed MGB-10 that they have already acquired consent from Eastwind Mining, which they believed has the ExPA over their mining operation is located. Thus, as per advised by LGU Opol, they are seeking for MGB certificate that they have already complied the MC 2007-07. To provide assistance to the clientele, MGB-10 immediately conducted field verification on August 5, 2008.



oplan huliIn a bid to stop all illegal hydraulicking operations within the Iponan River Watershed, a team composed of forty five(45) personnel from MGB 10, CENRO-Initao, 4th Infantry Division/Philippine Army, NBI 10, 10TH PNP Regional Mobile Group and Opol PNP Station was commissioned to conduct “Operation Huli” on February 13, 2009. This activity was hatched by the Technical Working Group of the Regional Minerals Development Council chaired by OIC RD Juanito A. Manzano, Jr of MGB-10, after a series of meetings held at DENR Region 10. The recurring problem of heavy siltation of Iponan River due to absence of forest vegetation and hydraulicking was believed to be a contributory factor to the flooding that recently hit Cagayan de Oro City.

Landslide Occurrence At Bagtukon, Malasag, Brgy. Cugman, Cagayan De Oro City

Posted October 12th, 2010 by Osin A. Sinsuat, Jr.

The landslide started on about September 1, 2010.  It was noted that it did not rain heavily the past two days.  The movement started from uphill of Bagtukon Creek.  The landslide materials were deposited on the creek bed, carrying with it uprooted trees (hardwood/forest and coconut trees) and soil materials. 
The volume of the materials deposited is estimated at about 10,000 cu.m.
There is a farmhouse immediately adjacent to the creek.  Coconut trees in the immediate vicinity uphill of the farmhouse were observed to exhibit creeping movement.  The inclined trees are indicative of potential mass movement.
Going downslope, Bagtukon Creek meets Malasag Creek before reaching the culvert, which then drains its load towards Biga-an River.
Aside from the farmhouse uphill, downslope along the road are about four houses in the immediate vicinity and the chapel.  Two of these houses are immediately along the creekbank.

Landslide Occurred At Sacred Heart Village, Sitio Zayas, Carmen,Cagayan De Oro City

Posted July 24th, 2010 by Marino B. Uncad and Osin A. Sinsuat, Jr.

A Landslide occurred on July 19, 2010 at Sacred Heart Village which is located at zone 8, Sitio Zayas, Brgy. Carmen, Cagayan de Oro City, which brought damages on one (1) classroom. Fortunately, there was no one inside the room during the event. The landslide partially damaged the wall of the classroom. Slide materials consists of mixed huge boulders and the granulated earth materials from the terrace gravel probably soaked with water.

Although there is no reported hurt by the random occurrences of mass movements coming from the very steep slope, the principal is concern on risk involve with the pupils and teachers. The mass movement progress to alarming level that could caused more damaging landslide overnight depending mainly on the amount of rainfall in the vicinity. The nearest school building is only 7 to 11 meters away from the foot of an artificial cliff, based on the interview made with the principal and on the observed piles of screed earth materials, landslide and other type of mass movements has long been occurring in this area.
