There was a resource upgrade on 17th Nov 2017:

Calibre Deposit Inferred Mineral Resource, estimated by Snowden Mining Industry Consultants, delivers a +50% increase in gold grade and ounces with 47.7 million tonnes grading 0.85 g/t gold and 0.15% copper for 1.3 million ounces of gold and 69,500 tonnes of copper.

The Calibre Mineral Resource estimate was compiled using relevant drill hole information derived from the ten diamond drill holes (4,482m) and 50 reverse circulation (RC) drill holes (8,489m) completed by the Company, from 2012 to 2015.

Then this year 2021, there was another resource upgrade for Calibre after 13,800m of drilling in 2019-2020:
