Global news and projects According to James Sinclair, executive chairman at Tanzanian Gold Corporation, the company has drilled a total of about 4 700m during the phase 1 pit infill drilling programme. "Our open pit and the substantive mineralised zones we are confirming both in, and below the pit continue to impress. I believe we are seeing our thesis of wider, deeper, richer being confirmed as we progress our drilling programme from phase 1 into phase 2. Intersecting 89.6m of continuous gold mineralisation outside and below the pit is spectacular and bodes well for our future," says Sinclair. Botswana Metal Tiger increases investment A digital representation of the new Centrex Metals Ardmore phosphate plant. costs by 13% due to key design changes and equipment selection. Simon Slesarewich, CEO at Centrex Metals, said since Centrex acquired Ardmore in 2017 the company had focused on producing high- quality phosphate rock concentrate to deliver this vital commodity for agriculture in Australia, which is presently heavily reliant on imports. “Following a thorough feasibility study, we expect to produce 776 000t of premium grade phosphate rock concentrate, which is equivalent to 800 000 wet tonnes per annum at the target shipping level of 3% moisture. “To deliver this target over the estimated 10- year lifetime of the mine, we required a reliable and resilient wet processing solution to remove the fine gangue after the high-grade ore has been crushed to meet sizing specifications. Our research showed that CDE could deliver a solution that fully met our requirements.” Concentrate produced from the start-up phase will go to potential offtake customers. Papua New Guinea Barrick wants to mine Porgera for 20 years Barrick president and CEO Mark Bristow and Zijin executive director and senior vice president George Fang, recently met Papua New Guinea’s new Prime Minister James Marape and reaffirmed the company’s commitment to working with the PNG government and local communities to ensure that the Porgera gold mine continues to deliver value to its stakeholders past the expiry of the current special mining lease on 16 August 2019. Since pouring its first gold in 1990, Porgera has paid more than PGK3.6-billion (USD1.1- billion) in taxes and PGK1-billion (USD297- million) plus PGK600-million (USD178- million) in equity cash payments and royalties respectively to the provincial government [8] MINING MIRROR AUGUST 2019 and customary landowners. This represents a significant contribution to the country’s economy, as well as a substantial amount to the landowners on whose properties the mine is located. An application to extend Porgera’s special mining lease for a further 20 years is currently in progress. Bristow says Porgera was an important long-term asset for PNG as well as the mine’s owners, Barrick Gold Corporation and Zijin Mining Group. “The proposed extension to its lease will allow the mine to remain productive for at least another 20 years. To sustain mine operations, however, it will require a significant capital injection, and it is difficult to justify that kind of investment without the security of an extended mine lease,” he says. Porgera is a joint venture between Barrick and the Zijin Mining Group, which each owns 47.5% with the remaining 5% interest being held by Mineral Resources Enga (owned equally by Porgera Special Mining Lease Landowners and the Enga Provincial Government). The mine is operated by Barrick (Niugini). Porgera is in the Enga Province of Papua New Guinea at an altitude of 2200-2700m. It is 130km west of Mt Hagen and 600km northwest of the capital Port Moresby. The mine employs more than 3 300 Papua New Guineans of which 1 900 are from Porgera and nearby Enga. Tanzania End of in-pit drilling Tanzanian Gold Corporation has announced results from three holes that bring an end to phase 1 of the in-pit drilling programme at its Buckreef gold project in Tanzania. Tanzanian Gold Corporation announced a three-phase drilling programme in January this year with the primary objective of phase 1 to upgrade inferred resources within the open pit and to add additional ounces. London Stock Exchange AIM-listed Metal Tiger has announced an additional USD1.1- million equity investment into Botswana focused explorer Kalahari Metals. Metal Tiger currently owns 50% of the issued share capital. The additional investment enables Kalahari Metals to complete its planned first round drilling at the Ngami copper project and the Okavango copper project, both in Botswana. The cutting of access tracks for the 2 100m diamond drill programme started, on schedule, last month, and drill rigs will be mobilised this week. According to Michael McNeilly, CEO of Metal Tiger, the additional funding allows Kalahari Metals to plan further work programmes over its licence holdings. “The Kalahari Copper Belt is highly prospective, and we are confident that continued exploration work in the region will potentially result in new, exciting copper discoveries,” says McNeilly. Ethiopia Altus goes for gold Altus Strategies’ Ethiopian subsidiary Altau Resources has been granted the Zager exploration licence in the Tigray National Regional State in northern Ethiopia. The Zager exploration license covers an area of about 285km2 in northern Ethiopia. The licence targets the Nakfa terrain of the Neoproterozoic Arabian Nubian Shield, which is considered highly prospective for polymetallic and gold-rich Volcanogenic Massive Sulfide (VMS) mineralisation, as well as orogenic lode gold deposits. According to Steven Poulton, CEO of Altus, a first phase reconnaissance exploration programme will include a field assessment of numerous remote sensing targets and a licence-wide stream sediment sampling survey to prioritise areas of interest. Zager is underlain by an almost identical geological terrain to that of Altus’s Daro project, located 80km to the east. The geology of this region hosts the Bisha mine owned by Zinjin Mining and the Asmara project owned by Sichuan Road & Bridge Mining Investment Development Corporation in Eritrea, about 135km north and north-east of Zager respectively. Zager is also just 10km northwest of the Harvest VMS project, which is being advanced by TSX-V listed East Africa Metals. www.miningmirror.co.za
