Mines and Geosciences Bureau, Regional Office VII (MGB 7) Identified Possible Site for “Minahang Bayan” Within the Province of Cebu
A team composed of technical personnel of the Mines and Geosciences Bureau, DENR-Region VII, conducted a joint preliminary verification in Brgy. Cogon Cruz, DanaoCity, CebuProvince on October 16, 2015. The verified site is situated at geographic coordinates 10° 30ʹ 44.7ʺ north latitude and 123° 59ʹ 30.0ʺ east longitude with an area of about 19.8888 hectares which is about four (4) aerial kilometers west southwest of Danao City proper. It is accessible by a paved barangay road from the city going to upland and interior barangays of Danao City then to about five hundred (500) meters foot trails to reach the site.
The area is underlain by a sequence of clastic sedimentary rocks belonging to the Middle Miocene Toledo Formation. The sedimentary rocks exposed are generally brown, moderately hard to hard and weathered. Some rock materials exposed along the side of the creek were generally light gray, dark gray to bluish gray, hyrothermally altered, silicified and argillized igneous rocks fragments, possibly originally of dioritic or andesitic affinity. Pyrite dissemination as fracture fills was notable in the altered/mineralized rock. The hydrothemally altered and gold-enriched rocks in the area is a good target for further exploration.
On May 5-6, 2016, a follow-through field campaign was conducted by technical personnel of MGB 7 together with the Danao S and M Producers Cooperative personnel. During the activity, thirteen (13) rock samples were taken in the area for laboratory analysis at private laboratories for gold contents. At present, results at analysis are not yet available.
Nonetheless, the initial observation indicates that the site is a potential good option for Declaration as Minahang Bayan area.
