"The results from this drilling will be included in an update to the Resource model and provides samples for planned metallurgical test work."

"Sunshine continues to increase its knowledge of the Plateau prospect and it is pleasing to read that Plateau is being considered as part of Sunshine's ambition to commence near-term, open cut gold mining. We commend Sunshine for their professional and diligent development efforts."
