I guess the question is, where is gold discovered and by whom?
The Portuguese won't find much gold on the coast of Brazil. Eventually they will probably set up sugar plantations as per OTL, but this will take them a while.
If Columbus sails for England, he will probably find gold or some mineral that's close enough to it, but the English will not really have a lot of power projection at that point compared to the Spanish. They also don't have sugarcane, so the Caribbean won't seem very useful to them without easy gold. We may still get filibusters, with English 'conquistadors' trying to take over land and reduce the Taino to servitude, but this will be a slower process than Spain's more systematic conquest of the Greater Antilles IOTL.
