La Mancha’s Greenheart Gold deal deepens Guiana Shield exposure

La Mancha Resource Capital invested C$50 million to buy 50 million shares of Greenheart Gold at C$1 each, lifting its stake to 19.9% from 4.6% and becoming the explorer’s largest shareholder. The financing, which G Mining Ventures is expected to join to keep its 10.5% stake, pushed Greenheart shares more than 10% to C$1.08 (C$157.3m market cap). La Mancha’s move — part of a broader push in the Guiana Shield after a prior $313m position-building in G Mining — signals growing institutional appetite for regional gold exposure and could buoy valuations of junior explorers. Greenheart’s promising Majorodam drill results (notably 15.3m at 3.72 g/t including 8m at 6.57 g/t) and a planned 10,000m follow-up program add technical momentum. Market impact: increased investor interest in Guiana Shield gold assets and potential upside for Greenheart and peer explorers; supportive for gold-mining sector sentiment.
