PVW Resources (‘PVW’, “the Company”) is pleased to provide an update on the metallurgical sighter testwork and mineralogical results at the Tanami Rare Earth Project.
Highlights
- Ore sorting and magnetic separation testing have been successful in upgrading the rare earth grade of samples while rejecting significant mass, indicating important potential to save on downstream processing costs.
- Ore Sorting obtained a TREO grade of 7.16% at a recovery of 87.3%.
- Magnetic separation obtained an 81.2% recovery and 50.8% mass rejection.
- Flotation testwork is being conducted on the magnetic separation concentrate to achieve a higher-grade concentrate suitable for downstream processing.
- Mineralogical studies continue to add to the understanding of mineralogy and ore paragenesis, assisting the geological understanding and exploration.

The metallurgy and mineralogy go hand in hand and both studies indicate the xenotime mineralisation will be recoverable using known processing technologies.
Studies on the five 20kg samples collected for metallurgical testwork by metallurgical consultants IMO are progressing well with encouraging results. The assay results of the five metallurgical samples were previously reported with an average HREO percentage of 80% including an average of 2,990ppm dysprosium oxide and up to 5,795ppm dysprosium oxide (see PVW:ASX announcement dated 1st February 2022 titled “Metallurgical samples highlight significant rare earths”).
Ore sorting and magnetic separation work on the samples is complete at a “sighter” level. The knowledge gained from these two steps will ensure ongoing flotation testwork is conducted on the most suitable material to achieve a higher-grade concentrate for downstream processing.

E-Tech Resources
Overview
E-Tech Resources (TSXV:REE, FSE:K2i) is a Halifax, Nova Scotia-based exploration company developing its high-grade Eureka rare earths project in Namibia, a top-tier and mining-friendly jurisdiction in Southern Africa. The company is focused on exploring for neodymium and praseodymium, two critical minerals necessary for the global energy transition goals.
Part of the rare earth elements (REE) family of minerals, neodymium and praseodymium are essential to high-performance magnets used for electric motors, generators and electric vehicles. As demand for REEs is expected to increase by 400 to 600 percent over the next few decades, the focus is shifting toward developing a supply chain outside of China, which has long been a dominant supplier of the world’s REE.
The company's fully owned flagship Eureka project is located in the Erongo Mining Corridor of Namibia. The Eureka project has a maiden inferred resource of 310 kt at 4.8 percent TREO with grades ranging from 1 to 16 percent. The company believes there is strong potential to increase the inferred and indicated mineral resource by at least 0.5 to 1.5 million tonnes, based on a technical scoping study.
E-Tech Resources completed a combined diamond drilling and reverse circulation drilling campaign at Eureka in 2022, with final assays indicating significant intersections of 11.2 meters at 1.2 percent TREO, 2.2 meters at 2.4 percent TREO, 8.8 meters at 1 percent TREO, and 6.3 meters at 1.9 percent TREO.
In addition, preliminary pXRF drilling results1 for the Adder Target have confirmed a discovery zone with the presence of REE mineralization identified in multiple zones in a drill hole correlating with REE mineralization identified on surface. Mineralization remains open at depth and along strike.
The results are part of the ongoing extended exploration of one of the 17 targets identified through ground radiometric and magnetic geophysical surveys and a geological mapping program completed earlier.
The Eureka project is strategically located near several mines and projects, including Rossing Uranium's Rossing Uranium mine, QKR's Navachab Gold mine, Namib Lead and Zinc Mining's Namib Lead and Zinc mine, and AfriTin's Uis mine. Eureka has excellent infrastructure and access to a major highway, a railway, roads, power, water and skilled professionals.
The company has taken steps to expand its land holdings within the Erongo Mining Corridor in Namibia, by entering into an agreement to acquire an 85-percent interest in EPL 874, which lies adjacent to and surrounds the company’s EPL 6762. The approximately 165-square-kilometer EPL 8748 contains a significant portion of the prospective Eureka Dome, the geological feature hosting mineralised REE-bearing carbonatites. Approximately a third of the Eureka Dome falls within the boundary of E-Tech Resources’ EPL 6762 and the remaining portion falls on the adjoining license EPL 8748.
E-Tech Resources is committed to maintaining the highest ESG standards to sustainably supply the green economy and adhere to the guidelines of the United Nations' Sustainable Development Goals. E-Tech Resources plans to create a sustainability committee to guide its ESG efforts and will be conducting further environmental and social impact assessments as part of ongoing feasibility studies to maintain responsible sourcing. E-Tech Resources' Eureka project is currently expected to have no major negative socio-environmental impact on the region.
The company is exploring the potential of a feasibility study for a rare earth separation plant in Namibia. Recognizing the need for a de-risked supply chain for these strategic critical raw materials, E-Tech is collaborating with Ondoto Rare Earth, a private Namibian company developing the high-grade Ondoto bastnaesite deposit in northern Namibia, and Namibia Critical Metals (TSXV:NMI, OTCQB: NMREF), which is developing the tier-1 heavy rare earth project, Lofdal, a globally significant deposit of the heavy rare earth metals dysprosium and terbium. Together, the three companies will participate in a joint venture known as Rare Earth Alliance Namibia (REAN).
E-Tech Resources also signed a memorandum of understanding (MOU) with Novamera to evaluate the use of surgical mining and Novamera's technologies as the extraction method for the Eureka Project. The MOU sets out a series of milestones that include a conceptual surgical mining economic desktop evaluation (commencing immediately), Guidance Tool calibration activities and a bulk sample which could provide a more cost-effective and faster path to production, while also radically reducing environmental and social impact.
After evaluating the results of the current exploration program, the company engaged Gecko Namibia and Flightec Namibia to support ongoing exploration and development activities on the project. Phase 1 ultra-high resolution UAV-borne magnetic survey will be conducted by Flightec.

High Priority REE Targets Identified At The Company’s Critical Elements Project
HIGHLIGHTS
- High priority REE (rare earth element) targets identified by expert geophysical consultants, Southern Geoscience
- Multiple radiometric anomalies and structural zones prospective for pegmatite intrusions identified
- REE targets are located on the Company’s exploration licences E09/2354 and E09/2377 in the highly prospective Gascoyne Province, Western Australia
- Initial exploration program to commence later this month, comprising ground reconnaissance, rock chip sampling and geochemical analysis
The high priority targets sit within tenements held by Reach Resources wholly owned subsidiary, Critical Elements Pty Ltd (Critical Elements), that were acquired in November 2021. The Critical Elements Project lies in close proximity to successful explorer Kingfisher Mining (ASX:KFM) and are also only ~80km south of the Company’s Skyline tenure, which is immediately adjacent to Hastings Technology Metals Limited (ASX: HAS “Hastings”), Yangibana REE development which has a current Ore reserve of 16.7Mt at 0.95% TREO for 158Kt (Refer HAS ASX Announcement 27 July 2021). (Refer to Figure 1).
Figure 1: Reach Resources regional locations
Southern Geoscience focussed on structural interpretation and target generation based on airborne magnetic data, with additional detail derived from interpretation of radiometric data and satellite imagery. Resulting from the interpretation was the identification of six REE targets within Reach tenure. A full list of identified targets within Reach tenure is included in Table 1 and depicted in Figure 2.
All targets display geological and structural complexity combined with previously identified prospective critical metal and/or REE mineral association.
Figure 2: Targets and Magnetics
Costeaning has been undertaken previously within the project areas and returned significant results including 12.4% Ta2O5, 32.0% Nb2O5, 0.95% WO3 and 0.25% Sn, from selective rock chip samples (Refer ASX Announcement 29 November 2021). REEs were not analysed at that time however thorium anomalism, which has been shown by Kingfisher Mining and others to be associated with REE mineralisation in the region, has also been identified on Reach tenure from the radiometric data for the area interpreted by Southern Geoscience.
