Other mineral deposits are silver, copper, pyrite, and limestone. Silver smithing is a large industry in Benguet, and many entrepreneurs sell silver works at lower prices in Baguio compared to Manila. In 2006, revenues from mining reached 4 billion pesos from just two (Lepanto Consolidated Mining Corporation and Philex Mines) of many mining firms operating in the province. The province's mining vigor has never translated into better quality of life of the Benguet people, simply because a bulk of the mining firm's taxes are not paid directly to the province. The two mining corporations, like many others around the country, have principal offices in the City of Makati, a set-up that makes Makati the prime mining tax beneficiary.
