CAPITAL MARKETS Lihir returns to production. LIHIR Gold returned to full production and operation early Saturday after fixing a problem with its Linde oxygen plant, allowing all three autoclaves to operate. Lihir Phase 14A PFS indicates potential for growth and large scale, long life, low cost production. Confirms Lihir's pathway to become a 1Moz+ gold producer for at least 10 years from FY24 1 . The Lihir gold mine is located on Niolam Island, Papua New Guinea (PNG), approximately 900km north-east of Port Moresby. The gold mine was managed by a subsidiary of Rio Tinto until late 2005, and the operatorship was then handed over to Lihir Gold. Australian miner Newcrest Mining acquired Lihir Gold in a bn deal in 2010.
The utilization of a pressure-oxidation circuit to treat refractory gold ores or concentrates is a complex decision, taking into consideration capital costs, operating costs, gold recovery, and environmental impacts. .

During the first five years of operation, the Lihir gold mine has steadily increased plant throughput rate to over 4 Mtpa, well above the original design capacity of 2.8 Mtpa. Understanding how future variations in ore type impact on plant performance has been an integral part of LihirÆs development program. This paper discusses the key drivers for significant . The Lihir ore deposit is a sulfide associated refractory gold ore of epithermal origin containing different types of pyrite with a range of levels for gold. The presence of the low gold pyrite types decreases the Au:S value of the Lihir ores and its concentrates resulting in higher consumption of oxygen in the autoclave and thereby affecting .The Lihir base case gold production schedule projects mini ng rates to increase up to 50Mtpa over the coming years and an average milling rate of 15.5Mtpa9. Ore from Phase 14A is expected to be mined between FY22-26 and will be processed over the LOM. Figure 5: Lihir LOM indicative gold production profile9-500 1,000 1,500 Gold produced (koz) The Lihir deposit in Papua New Guinea (PNG) contains an estimated mineable reserve of 13.7 million ounces of gold in refractory sulphide ore. RTZ, through its subsidiary Kennecott Corporation and in joint venture with Niugini Mining Limited, has submitted a conditional proposal to the PNG government to develop an open pit mine and to install a .

Pressure oxidation of sulfides at Lihir is in the range of 50 to 90%, and this operating strategy is used to maximise gold recovery through selective oxidation (Gardner et al., 2017) to overcome the otherwise low Au:S ratio of the autoclave feed caused by the presence of low gold pyrite.If a concentration step such as flotation could separate one specific type of .
Gold extraction from well washed ore, after oxidation at 210°C for 66 minutes in the autoclave, was typically between 94 and 96%, compared with less than 30% by direct cyanidation. The bulk of the ore found in the Lihir Island deposit is refractory in nature, with the gold contained in auriferous pyrite.
record gold production to be achieved. Autoclave feed for the quarter included almost 200,000 tonnes of flotation concentrate, which combined with higher grade ore from the pit, lifted autoclave feed gold grade to 7.1 grams/tonne.

Summary: The Lihir deposit is considered to be an example of an epithermal gold deposit. Lihir Island is part of a 155 mile (250-kilometers) long, northwest-trending, alkalic volcanic island chain that sits within an area where several micro-plates (Solomon Sea Plate, South Bismarck Plate and North Bismarck Plate) developed between the converging Australian and South Pacific plates.
