With an estimated 300,000-500,000 miners operating in more than thirty provinces across the country2, the Philippines is one of the more significant artisanal gold producers worldwide. According to the official records of the Philippines Central Bank, artisanal producers in 2018 generated just under US$14 million worth of gold, or about 350kg. Given that many artisanal producers in the Philippines work informally, the real figure is certainly much higher. In total in 2018, the  Philippines generated 36.8 tons of gold1, worth about $1.5 billion at world prices. With the advent of COVID-19, the 2020 production figures are likely to drop sharply, and the selling price already has dropped significantly, so miners and their families are already seeing an income cut.
