Several waterbodies have been declared as natural wetlands in the country supporting the needs of community like water and food. In this study, 65 natural wetlands were considered including six sites that were identified as ‘Wetlands of International Importance’ such as Naujan Lake National Park, Agusan Marsh Wildlife Sanctuary, Olango Island Wildlife Sanctuary, Tubbataha Reefs Natural Park, Las Piñas-Parañaque Critical Habitat and Ecotourism Area and Puerto Princesa Subterranean River National Park. There are 22 wetland types presented in this research categorizing the Philippine wetlands. Philippine wetlands are now facing tremendous challenges such as land use conversion, abuse of resources, pollution coming from domestic, industrial and agricultural activities, and climate change. This paper provides an overview of Philippine wetlands in terms of their characteristics and components, impacts in the ecosystem, and the challenges they are dealing with.

Here, we provide a limnological characterization of the lake – exploring its physical, chemical, and biological features. The data on lake morphometry were gathered using an echosounder; lower depth water samples were collected using a Niskin water sampler for physicochemical analyses while surface water samples were collected at five sampling sites for phosphate (PO4) analysis; and zooplankton samples were collected at several depths through vertical towing in March–April 2019. Lake Wood, located at 320 m above sea level, has an extensive surface area covering 7.38 km2 with a maximum depth of 85 m. Lake water comes from rainfall, small rivers, and groundwater and empties into the Dumanquilas Bay via its only outlet – the Biswangan River. Land use of the lake is predominantly cultivated land. Moreover, based on the trophic state index (TSI), the lake’s current trophic status is eutrophic. During the study periods, thermocline and oxycline formed at 15 m below the surface of the lake.

Teresa and Masara, Maca, Compostela Valley Province in the southeastern part of Mindanao Island, originally existed as contiguous load claims comprising of 75 Declaration of Locations (DOLs) of nine (9) hectares each and a number of claim fractions of various shapes and sizes with a total area of 679.02 hectares. The claims, named ASA·24, et ai, were originally staked for gold, copper, silver and other metallic minerals under the Philippine Bill of 1902. Prior to the MPSA Contract approval, the area was covered by Mining/Lode Lease Contract Nos. Y·83; Y·95; Y·96, Y·97, Y-124 and Y-125 which were issued in 1994 to Apex Mining Company, Inc. The MLCs were subsequently applied for Mineral Production Sharing Agreement by Apex in 1998, denominated as APSA·242·XI. An amendment was filed by Apex for the same APSA in January 2005.

    Integrated remote sensing in determining areas of high geothermal potential in the exploration of the Amacan Geothermal Prospect, Philippines Jeffrey T. Bermido, Kevin G. Guillermo, Oliver A. Briola, Leonardo L. Morales, Releo D. Contemplacion, and Joeffrey A. Caranto Energy Development Corporation, One Corporate Center, Julia Vargas cor. Meralco Ave, Ortigas, Pasig City, Philippines [email protected], [email protected], [email protected], [email protected], [email protected], and [email protected] ABSTRACT Leonard Kniassef is one of the active volcanoes in the Philippines, located in the eastern portion of Mindanao Island. It is interpreted to host the high temperature Amacan geothermal system, known for its Quaternary volcanism set on a favorable structural environment. In order to identify priority areas for detailed exploration, this study integrated three remote sensing techniques with minor statistics application namely: lineament analysis, hydrothermal alteration, and thermal anomaly mapping. Digital elevation models were processed for the lineament analysis, where slope statistics were correlated with the underlying tectonics. Thermal Infrared Sensor Band 10 of Landsat 8 was also processed using a series of raster calculations to highlight areas with high surface temperatures. The Operational Land Imager (OLI) bands of Landsat 8 were also processed using composite and band ratio operations to highlight alteration zones and discriminate the type of alteration present. Combining the three remote sensing results, five priority areas are identified to have high geothermal potential and activity. These areas are recommended for more detailed geoscientific assessments. Keywords: remote sensing, geothermal exploration, lineament analysis, hydrothermal alteration, thermal mapping 1.

    2017 UPDATE ON THE MACO GOLD PROJECT Compostela Valley, Philippines Prepared for: Apex Mining Company Inc. Figure 1-1: Massive Sulphides of the Sandy North Vein CP involved Rolando E. Pena BS Geo Registered Geologist, Lic. No. 068 CP Exploration Results and Mineral Resource Estimation, PMRC/GSP CP Reg. No. 07-08-08 December 2016 1 | R . E . P e ñ a 3.0 EXECUTIVE SUMMARY APEX Mining Company Inc. contracted Rolando E. Peña (Registered Geologist No. 068; CP - Geology No. 05) to review and audit the resource estimation prepared by the Apex Technical Services Team, and to certify compliance of the said estimate with the Philippine Mineral Reporting Code. The Maco Mine is within the Southern Pacific Cordillera, identified as a magmatic arc terrane bounded by the left-lateral Philippine Fault to the west and the Philippine Trench to the east. The regional geology is characterized by a Cretaceous-Paleogene volcanic basement comprising the Barcelona Formation, overlain by the Eocene sedimentary sequence identified as the Tagabakid Formation. The Early-Middle Miocene Agtuuganon Limestone unconformably overlies the sequence. Quartz diorite bodies of the Cateel Quartz Diorite have been mapped to intrude these stratigraphic units. The geology is capped by the Pliocene- Pleistocene Amacan Volcanic Complex. The andesitic basement rocks mapped within the tenement, locally identified as the Masara Formation, could be correlated to the regional Barcelona formation, while the Miocene diorite intrusives might be coeval to the Cateel Quartz Diorite. Young dacitic and andesitic units of the Amacan Volcanic Complex are widespread in the Maco mine. Gold veins in the tenement are hosted by the older andesite and diorite units limiting the age of mineralization to older than the Amacan Volcanic Complex.

SHORT COURSE MANUAL DRAFT as at 24 May 1997 G J Corbett and T M Leach Short course manual: Southwest Pacific rim gold-copper systems: Structure, alteration and mineralization, G Corbett & T Leach, 5/97 Edn. SUMMARY This manual classifies and describes differing styles of southwest Pacific rim gold-copper systems, and analyses hydrothermal ore-forming processes. Investigations of these systems in terms of structure, alteration and styles of mineralization provide information which may help determine the direction of fluid flow within evolving hydrothermal systems. Major structures localize magmatic hydrothermal systems in magmatic arc settings and create ore-hosting dilational environments within subsidiary structures, commonly at high angles to the controlling structures. Differing styles of convergence influence the style of major structures and ore-forming environments. Breccias occur in most gold-copper deposits and may be categorised as a guide to understanding the ore-forming environment as broad correlations are apparent between breccia and mineralization styles. Temperature and fluid pH are considered to be the most important of many factors which control the types of hydrothermal alteration. Hydrothermal minerals are classified in terms of these two factors to create a meaningful interpretation of alteration data.
