David Price, Chief Executive Officer of Rockfire, commented:

"These silver grades are very pleasing and may add to the future economics of the project."


"The use of the portable XRF machine acts as a guide to mineralisation and analysis using proven laboratory techniques such as Inductively Coupled Plasma (ICP) is required to determine a definitive silver assay. Rockfire intends to submit these highly anomalous samples to the lab for definitive analysis. In addition to the silver, elevated and anomalous zinc and lead are also present and the Company intends to submit these samples for further analysis also."


"We are eagerly awaiting the results of our recent drilling campaign at Plateau and the Company is pleased to inform the market that samples have now been delivered to the laboratory in Townsville. Further announcements will be made as results become available."



XRF parameters


The XRF analyses were completed on samples which were professionally prepared by Australian Laboratory Services Ltd. The preparation includes crushing and pulverising the entire sample to produce a homogeneous sample. The XRF analyses were completed by Terra Search Pty Ltd, an independent service provider. The XRF model used was a Niton XL5 and each sample was analysed for a nominal 60 seconds. The calibration mode used was the Niton standard mining mode.
