The company said three rigs were drilling at the Villa Rica target, Norte and Porvenir zones.
Azucar formed as a renamed Almadex Minerals in May to focus on its El Cobre discovery, gaining C$19 million (US$15 million) backing from a subsidiary of Australian-based gold producer Newcrest Mining (ASX: NCM).
At the time, the company spun out its early stage exploration projects into a new Almadex Minerals.
Newcrest topped up its holdings in October at 55.81c per share to maintain its 19.9% stake in Azucar.
The explorer said it was permitted and funded for "an active drill campaign in 2019", having reported working capital of $15.8 million (US$11.7 million) at the end of September.
Azucar shares closed down half-a-cent to 38.5c yesterday, close to a 52-week low, to capitalise it over $28 million.
