THE MINERAL INDUSTRY
 IN THE PHILIPPINES
AMERICANS PROMISE TO MAKE
 IT VALUABLE ASSET.
Investigation Has Greatly Improved the Prospects-A Variety of Miner als Present in the Islands Suscepti- ole to Profitable Development

The outlook for a profitable mining industry in the Philippines Islands is more hopeful today than it has been al any time since the American occu- patton. according to a brief report written by Mir. H. D. McCaskey, chief of the Mining Bureau, Philip pine Islands. and published as an ex- tract from the annual volume of the United States Geological Survey en- titled Mineral Resources of the UDiJ- ed States. 1904" Mineral develop ment is now carried on in the prov inces of Pepanto- -Bontoc Benguet, Pangasinan Nueva Ecija, Bulacan, Rizal, Batangas, Tayabas, Camarines, Albay. Masbate, Cebu and Mindanao and prospecting is being done in a. most every island and province of thS archipelago.
 Gold and alyer have been found in LuZon and Visayas. h Suyoc, just south of Mancayan. LepantO. impOr- tant prospects are being developed by American miners at the present time.
 Gold and copper ores' both occur here In Benguet important develop
  ly in the district of Antamok. The ore bodies are apparently very exten- sive, and it is gnown that much of the ore is of a good grade. varying through the district from s to $50 per ton in gold, the most important pay steaks now worked averaging oyer SIP per ton. Much of the ore so far uncovered is free-milling Tn the Bataan district the Philippines Gold Mining, Power and Development Company has opened a number of drifts, but has not yet succeeded in getting it's 10-stamp mill upon the ground. In the Bued River district Messrs. Hanson and Meade have un- covered a rich gold-copper lead. upon which a 3-stamp mill will be erected at once In this district also are outcrops of lead, iron, copper and zinc sulphides, carrying s20 to the ton in gold. In Pangasinan. in the foot hills of the northernZambales range, near SalaSa, number of claims have been recorded and worked. The ores here are copper carbonate and sul- phites. In Nueya Ecija. near Gapan. and Penaranda, on the Rio Chico and elsewhere extensive deposits of plac- CT gold have been known for many years. No veins are yet reported, but prospecting in the placer ground is being actively prosecuted at the present time. h Camarines Prov ince the Spanish concessions upon the extensive gold deposits in the districts of Parscale and Mambulao have been largely relocated by American mining men under the present laws and some work has been done in the reopening Of abandoned shafts and in prepare tion for future systematic develop ment. The ores are sulphides of iron, copper. lead and zinc, in part com plex smelting ores and in part suit able for milling and cyanidation or chlorination. The placers have yield ed important amounts of gold in the past. some of the nuggets being un- usually large. In Marbate, near the town of ArorOy, in the northern part of the island more or less work has been done upon so or more claims, principally of free-milling gold ores in quartz, and upon 20 or more gold placer claims on the Lanan and Guina- balan rivers. Manganese and iron ores of high grade have also ben found here. but litle attention has been giv- en to them up to the present time.
