Hi mate, the overall resource is 2000 000 oz which includes reserves of 624 000 oz.
Like you say it should increase with the discovery at Manwe, Julie deposits and further drilling which will be included in the JORC update
The term "reserves" just means that through intensive drilling they have determined with a high degree of certainty that 624 000 oz is economically viable for extraction. As the project moves forward they will convert more of the resource to reserves through drilling.
