  "account": "Marimaca Copper has discovered a thick copper-silver zone at Pampa Medina in Chile's Antofagasta Region. The company's drilling at the site has revealed a 216-meter interval grading nearly 1% copper and 7.2 grams silver per tonne. The mineralization extends an additional 300 meters beyond earlier holes. Sergio Rivera, Marimaca's Vice-President of Exploration, stated that Pampa Medina remains open in several directions and is materially under-tested. The company plans to drill 30,000 meters at Pampa Medina this year, which could provide a growth source alongside their already-feasibility and environment-reviewed project. Shares of Marimaca's Toronto-listed stock jumped 13% on Tuesday, reaching $9.10 apiece and giving the company a market capitalization of $1.2 billion.",
