Portia gold processing plant
PORTIA HIGH GRADE GOLD ORE PROCESSING COMMENCED
HIGHLIGHTS
Havilah Resources Limited ("Havilah" or "Company") is pleased to report that after two weeks of commissioning, its processing plant is now processing high grade gold ore. The commissioning phase has progressed from running water to treating low grade ore and finally treating high grade ore.
With the processing plant ramping up to design capacity and steady operations, the processing of high grade gold ore has now commenced. Concentrates from the riffles and Knelson concentrators show that both pieces of equipment are recovering free gold particles over a wide size range (see photo below). Ore is being sourced from the stockpile generated from mining the interim sub-pit, as previously reported, with there being sufficient material available for treatment for several weeks.
The Portia open pit wall has experienced a slip in an area where ore was previously mined. This area had been showing signs of movement for several months, both visibly and on laser scans, and was being closely monitored at the time. As a matter of prudence, Consolidated Mining and Civil (CMC) has decided to temporarily suspend their mining operations in order to allow geotechnical experts to study the geometry of the slip and carry out back calculations of the material strength. The slip provides critical live data that can be used to test, re-calibrate and

update past geotechnical models. The objective is to provide updated guidance on the safest and best mine design going forward in order to minimise the risk of any further pit wall slips.
Commenting on recent developments, Havilah Managing Director, Dr Chris Giles, said:
"We are pleased to have commissioned our gold plant and see it operating according to design.
"Although I have often said it is a "simple" gravity plant, there is no room for error if we are to maximise gold recoveries.
"We fully endorse CMC's cautious approach in having geotechnical experts review the current mine design and identify any suggestions for modifications going forward that will reduce the likelihood of future pit wall slips. "Fortunately, we have plenty of ore stockpiled so production of gold from our processing plant will not be affected while this geotechnical study is being concluded" he said.
