HALIFAX, NS / ACCESSWIRE / October 7, 2021 /(“Namibia Critical Metals” or the “Company” or “NMI”) ( ) is pleased to provide an update on the development of the Lofdal Heavy Rare Earth project since granting of the Mining Licence in July this year. The Lofdal Heavy Rare Earth Deposit is one of only two primary xenotime projects under development in the world. The deposit has the potential for significant production of dysprosium and terbium, the two most valuable heavy rare earth elements used in high powered magnets and other high-tech applications. The Project is being developed in joint venture with Japan Oil, Gas and Metals National Corporation (“JOGMEC”) targeting a long term, sustainable supply of heavy rare earths to Japan.
The Company has successfully completed hydrometallurgical test work to develop a flowsheet capable of producing a high-grade rare-earth oxide product from a xenotime flotation concentrate. The Company’s lead metallurgical consultants at SGS Minerals Services Canada (SGS) have simplified the final process stage with an acid bake to crack the mineral xenotime, to purify the pregnant leach solution and to precipitate a rare earth oxalate, which is subsequently calcined to form a product containing >98% total rare earth oxides (TREO). The acid bake process and concurrent removal of impurities is highly efficient and resulted in a 95% recovery of Dysprosium and Terbium in the leaching operation of the processing flow sheet. The high-quality product is practically free of typical deleterious elements like thorium and uranium (<3 ppm combined U+Th).
Darrin Campbell, President of Namibia Critical Metals stated:
These very positive test results are another big milestone for the Lofdal project and show that we are on the right path towards establishing that Lofdal can produce a valuable heavy rare earth product. This will allow us to advance an updated assessment of large-scale and integrated rare earth production towards a high purity Rare Earth Oxide product in Namibia. This would result in further value addition in Namibia and puts the country on the global map of rare earth supply strategies.”
Hydrometallurgical test work and results
Two flotation concentrates produced by processing of bulk samples from the Lofdal deposit were tested at the laboratories of SGS in Lakefield, Ontario, to determine the potential for producing a marketable rare earth product with minimal impurities. Previous hydrometallurgical test work had focused on more costly caustic cracking following gangue acid leach. The comprehensive test work at SGS has demonstrated the acid bake route is preferred due to lower reagent costs and higher recovery of the heavy rare earths.
A total of 12 acid bake and water leach tests were completed throughout the test program to investigate the dissolution of rare earth elements (REE) and the behaviour of gangue minerals through the addition of sulphuric acid at elevated temperatures (200-300°C). Optimum results were achieved using an acid addition of 1250 kg/t H2SO4 at 300°C followed by a water leach at 20% solids by weight at 25°C. Under these conditions, the tests showed very good REE recoveries with 97-98% for yttrium, 95% for dysprosium and 94-95% for terbium.
Table 1: Elemental composition of the calcined oxalate
Impurity removal test work using magnesium carbonate and hydrogen peroxide resulted in maximum precipitation of iron and thorium from the pregnant leach solution while minimizing REE co-precipitation. An intermediate and impure REE precipitate was produced via the addition of soda ash (sodium carbonate) solution.
The intermediate REE precipitate was re-leached in sulphuric acid using a two-stage sulphuric acid process at 50°C to achieve a pulp pH of around 3.5. This step resulted in the production of a concentrated REE liquor representing 99% of the available REE and also rejected 94% of the thorium, 85% of the aluminum, and 99% of the remaining iron.
To remove residual uranium and thorium, the re-leach liquor was processed through sequential ion exchange (Purolite A660) and solvent extraction (0.5% Primene JMT, 2.5% isodecanol in Aromatic 150ND) steps to selectively remove uranium and thorium from the REE liquor. Consequently, 99.9% of the uranium was removed in the IX contacts. A significant fraction (94%) the thorium was also removed in the IX steps and 75% of the remaining thorium was removed in the solvent extraction steps. The practically thorium-free raffinate from the solvent extraction step advanced to final REE precipitation with oxalic acid and calcination of the REE oxalate.
In the REE oxalate precipitation step, all REE were precipitated with minimal co-precipitation of impurities such as sodium, magnesium, silica and calcium. The final REE oxalate was calcined and produced a final solid containing 98.1% total rare earth oxides (TREO) or 86.2% of heavy rare earth oxides (HREO). High leach extractions of ~95% were achieved in the test program and REE losses in the REE recovery steps (as shown in Figure 1) are expected to be minimal.

While the results are extremely positive, there remains room to optimise these processes regarding OPEX and CAPEX as well as recoveries. This final optimisation on flotation concentrate produced from the currently mined bulk samples is planned for 2022.
Planning for further value addition in Namibia
The positive hydrometallurgical test results allow for planning of value addition beyond the production of a xenotime concentrate at the Lofdal Mine providing for a win-win for the country and the company.
The addition of a hydrometallurgical plant would create further jobs in the southern Kunene Region of Namibia, and provides a marketable product for export as the rare earth oxalate with thorium and uranium levels below 3 ppm would be acceptable for import into Japan without restrictions or penalties.

Heavy Rare Earths: The Lofdal Dysprosium-Terbium Project is the Company’s most advanced project being fully permitted with a Mining Licence (ML 200) issued in 2021. The project is being developed in joint venture with Japan Oil, Gas and Metals National Corporation (“JOGMEC”) to provide a sustainable supply of heavy rare earths to Japan, most notably dysprosium and terbium.
Gold: The Company’s Exclusive Prospecting Licenses (“EPLs”) prospective for gold are located in the Central Namibian Gold Belt which hosts a number of significant orogenic gold deposits including the Navachab Gold Mine, the Otjikoto Gold Mine and more recently the discovery of the Twin Hills deposit. At the Erongo Gold Project, stratigraphic equivalents to the meta-sediments hosting the recent Osino gold discovery at Twin Hills have been identified and soil surveys are progressing over this highly prospective area. The Grootfontein Base Metal and Gold Project has potential for magmatic copper-nickel mineralization, Mississippi Valley-type zinc-lead-vanadium mineralization and Otjikoto-style gold mineralization. Detailed interpretation of geophysical data and regional geochemical soil sampling have identified first gold targets, with the first targets currently being drill-tested.
Tantalum-Niobium: The Epembe Tantalum-Niobium-Uranium Project is at an advanced stage with a well-defined, 10 km long carbonatite dyke that has been delineated by detailed mapping and radiometric surveys and over 11,000 meters of drilling. Preliminary mineralogical and metallurgical studies including sorting tests (XRT), indicate the potential for significant physical upgrading. Further work will be undertaken to advance the project to a preliminary economic assessment stage.
Copper-Cobalt: The Kunene Copper-Cobalt Project comprises a large area of favorable stratigraphy along strike of the Opuwo cobalt-copper-zinc deposit. Secondary copper mineralization over a wide area points to preliminary evidence of a regional-scale hydrothermal system. Exploration targets on EPLs held in the Kunene project comprise direct extensions of the cobalt-copper mineralization to the west, sediment-hosted copper, orogenic copper, and stratabound manganese and zinc-lead mineralization.

New High-Grade Gold Exploration Discovery at the Golden Marmot Zone Affirms the District-Scale Potential of Brucejack with 72.5 g/t Gold Over 53.5 Meters, including 6,700 g/t Gold Over 0.5 Meters
VANCOUVER, British Columbia, Oct. 25, 2021 (GLOBE NEWSWIRE) — Pretium Resources Inc. (TSX/NYSE: PVG) (“Pretivm” or the “Company”) today announced…
VANCOUVER, British Columbia, Oct. 25, 2021 (GLOBE NEWSWIRE) —(TSX/NYSE: PVG) (“Pretivm” or the “Company”) today announced a new high-grade gold exploration discovery at the Golden Marmot Zone on its Brucejack Property in Northern British Columbia. The Golden Marmot Zone is located 3.5 kilometers north of the Valley of the Kings deposit.
To date, assays have been received for the first nine drill holes of which eight drill holes intersected gold. A highlight was drill hole SU-786, which intersected four bands of high-grade gold mineralization over 53.5 meters.
Selected highlights include:
- SU-786 intersected 72.5 grams per tonne gold over 53.5 meters, including 6,700 grams per tonne gold and 3,990 grams per tonne silver over 0.5 meters and including 787 grams per tonne gold over 0.5 meters.
- SU-778 intersected 46.1 grams per tonne gold over 5.8 meters, including 208 grams per tonne gold over 1.0 meter.
- SU-772 intersected 22.8 grams per tonne gold over 38.0 meters, including 268 grams per tonne gold over 1.0 meter and including 188.4 grams per tonne gold over 2.13 meters.
See Table 1 below for assays received to date from the 2021 exploration program at Golden Marmot. For a plan and section view of the 2021 Golden Marmot Zone drill program and photos of the drill core please see the following link: http://ml.globenewswire.com/Resource/Download/749bcf27-7b97-4cc1-8410-a4735215a7f3.
“Initial results from Golden Marmot are exciting and affirm the district-scale potential of the Brucejack property,” said Jacques Perron, President and Chief Executive Officer of Pretivm. “The gold mineralization intersected at Golden Marmot occurs in the same host rocks and with the same alteration signature as the nearby Valley of the Kings deposit, which is a strong indication it could be a new high-grade deposit. Its proximity and existing trail access would make it relatively easy to integrate into future mine plans as an independent source of ore to supply the Brucejack mill.”
“The drilling completed in 2021 intersected gold mineralization over a zone that is approximately 150 meters in width, 250 meters in length, and 275 meters in depth. A historic drill hole intersected high-grade gold mineralization a further 225 meters below the currently drilled zone. The Golden Marmot Zone remains open and could be of similar size to the Valley of the Kings deposit. We are eagerly awaiting the assay results from the remaining 17 drill holes which we expect to release early next year.”
“These results continue to support our view that additional deposits and sources of high-grade mineralization will be identified near the Valley of the Kings deposit opening up the potential for a significantly longer mine life and continued impressive cash flow generation. Golden Marmot is only the first of several zones drill tested this year with results still to come from Gossan Hill, Bridge Zone and Hanging Glacier. All of these targets have the potential to deliver game-changing results and are within four kilometers of the Brucejack Mine infrastructure. We look forward to continuing to grow the potential of this exceptional property and will release results as they become available.”
The Golden Marmot Zone is located 1.75 kilometers east of the Hanging Glacier Zone where a gold discovery was made last year (see news release dated December 16, 2020). Both zones are part of a four-kilometer trend of highly altered rocks which outcrop from Hanging Glacier Zone northwest of the Brucejack Mine to Bridge Zone southeast of the mine.
The 2021 drill program at Golden Marmot consisted of 26 drill holes totaling 8,466 meters. Previous drilling completed in 2011 at Golden Marmot intersected 2.8 grams per tonne gold over 17.3 meters, including 23 grams per tonne gold over 1.3 meters in hole SU-197 (see news release dated September 12, 2011). This mineralized structure is located approximately 225 meters below the deepest mineralization intersected in the 2021 drilling.
Golden Marmot Zone
The Golden Marmot Zone is accessible via an exploration trail from the Brucejack camp and is marked by a prominent gossan on the hill side. Mineralization occurs as coarse-grained electrum hosted within silicified and quartz-sericite-pyrite altered conglomerates and sandstones, which is the same as the Valley of the Kings deposit.
The 2021 Golden Marmot drill target was defined by prospecting during the 2019 and 2020 field programs, with grab samples assaying up to 8.73 grams per tonne gold. To compliment this field work and aid in target selection, a prospectivity mapping and target ranking initiative was initiated with GoldSpot Discoveries Corp earlier this year. Artificial intelligence and machine learning algorithms were applied to synthesize the geochemical, geophysical and hyperspectral data available from the Brucejack Property. This program identified 65 targets on the Brucejack Property, with Golden Marmot ranking as a high priority drill target for quartz vein hosted gold mineralization.

Roscan Gold Announces Positive Metallurgical Testing Results From the Kandiole Gold Project Achieved 97.6% Recoveries for Oxide and 92.9% for Fresh Mineralization Samples at Flagship Mankouke South Target
TORONTO, ON / ACCESSWIRE / October 25, 2021 / Roscan Gold Corporation ("Roscan" or the "Company") (TSX-V:ROS; FSE:2OJ; OTC PINK:RCGCF) is pleased to announce…
TORONTO, ON / ACCESSWIRE / October 25, 2021 /(“Roscan” or the “Company”) ( ; FSE:2OJ; OTC PINK:RCGCF) is pleased to announce results from the metallurgical test work program completed on samples from gold prospects at Mankouke South (MS1), Mankouke Center- Kandiole (KN1) and the Kabaya (KB1- KB2) within the Company’s land package called Kandiole Projects located in west Mali, Africa.
- All of the samples representing the deposits (Mankouke South MS1 and Center, Kandiole KN1 and Kabaya KB1-KB2) tested in this program exhibit non-refractory metallurgical features, indicating that a simple, industry-standard cyanide leach process provides excellent gold and silver extraction.
- Total gold recoveries by gravity, plus 48 hours of CIL on all prospects, have averaged 97% for oxide (saprolite) samples, 89% for a transition sample and 90% for fresh mineralization samples.
- Flagship Mankouke South achieved 97.6% in the oxide and 92.9% in fresh rock.
- Both Oxide and Fresh mineralization are amenable to gravity concentration to recover free gold within the milling circuit.
- The gravity recovery average from all samples and CIL tests is 23%.
- The coarse ore leach tests in two Kabaya saprolite samples, to examine heap leach amenability, provided an average of 79% recovery of gold and 93 % silver after 8 days.
- One sample reached 88.4% gold recovery after 72 hours.
Nana Sangmuah, President and CEO, stated, “This is a major de-risking milestone for the Kandiole project confirming simple processing flow sheet with Oxide recoveries 97% including average gravity recoveries of 23% and up to 58% in certain deposits. We are also encouraged by the potential for silver by-product credits at our relatively lower grade Kabaya deposit which should further bolster project economics.”
Table 1: CIL and Gravity Test Recovery Summary
Table 2: Bond Work Index
All results from the gravity plus carbon in leach tests were positive, indicating that:
- The program included testing of gravity separation, grindability and grind size variability, agitated leach kinetics, Carbon in Leach (CIL) and for two of the composites, Heap Leaching amenability determinations. Results from this metallurgical test work provide significant progress in the Resources estimation process.
- A simple gold processing flowsheet for these deposits (Mankouke South MS1 and Center – Kandiole KN1 – Kabaya KB1- KB2) is applicable and will be considered in the maiden Mineral Resource estimation.
- The CIL results for the oxide zone, which carries a large proportion of the mineralization (70-80%) at Mankouke South MS1 and Center – Kandiole KN1 – Kabaya KB1- KB2, are particularly favorable with 97% total gold recovery.
- From different metallurgical tests, in Mankouke South, the most important portion of the overall mineralization, the gravity recovery reached 27% in saprolite and 25% in transition-fresh rock.
- In Kandiole, the gravity extraction varies from 48 % to 58%, and in Kabaya the average is 23.3%.
- Silver content of the Kabaya samples reaches 8.6 g/t with an average of 3.6 g/t and recovery in the gravity plus leach tests is above 95% for the saprolite.
- After further analysis of more Kabaya samples, the assays could demonstrate that Silver is a potential economic by-product.
- Encouraging leach kinetics indicate excellent gold extraction within 24 hours and averages only 0.5% below the extraction obtained in the maximum time of 48 hours.
- Bond Ball Mill Grindability of 3.3-6.2 kWh/t (saprolite) – 10.4-21.5 kWh/t (transition-fresh rock) is comparable to other gold operations in the region.
- Overall, the cyanide and lime consumptions indicated in this preliminary testing seem typical for these types of deposits.
In total, 12 composite samples of 20 to 40 kg have been sent for the metallurgical test work: 2 saprolite (oxide), 1 transition and 2 fresh rock samples from Mankouke, 1 saprolite (oxide) sample from Mankouke Centre, 1 saprolite (oxide) sample from Kandiole and 4 saprolite (oxide) and 1 fresh rock sample from Kabaya. Each composite comprised 1/3 of low-grade (0.3-1 g/t), 1/3 of medium-grade (1-3 g/t) and 1/3 high-grade (> 3g/t) drill sample intervals (all g/t values stated are for gold only).
For Mankouke South, the fresh rock has been separated between sedimentary and felsic intrusive rocks. Most of the composite samples have been prepared from ¼ of NQ diamond drill core, one composite was RC samples only and three have been prepared with a mix of core and RC samples. All individual samples which comprise the composites are well distributed spatially in the mineralization.
The test work was undertaken by Base Metallurgical Laboratories, Vancouver, Canada 200-970 McMaster Way, Kamloops, BC, Canada, V2C 6K2. The samples have been selected by Pascal van Osta, Roscan’s VP Exploration.
