The dispute went unmentioned for many years until gold was discovered in the region, which disrupted relations between the United Kingdom and Venezuela. In 1876, gold mines inhabited mainly by English-speaking people had been established in the Cuyuni basin, which was Venezuelan territory beyond the Schomburgk line but within the area Schomburgk thought Britain could claim. That year, Venezuela reiterated its claim up to the Essequibo River, to which the British responded with a counterclaim including the entire Cuyuni basin, although this was a paper claim which the British never intended to pursue.
