Power Metallic Demonstrates Positive Initial Mineralogy Results - PGE Enrichment Associated with Chalcopyrite and Cubanite
Power Metallic Mines (OTCBB:PNPNF) has announced encouraging preliminary mineralogy results from its Lion Zone deposit. The company's detailed microscopic scans, conducted by IOS Geosciences, reveal that copper mineralization is present in coarse-grained chalcopyrite and cubanite, which should respond well to conventional sulphide concentration methods.
The study shows that PGE minerals are primarily associated with chalcopyrite and cubanite, suggesting potential for efficient recovery in copper concentrate. The identified PGE minerals include stannopalladinite, froodite, and merenskyite, similar to those found in Sudbury basin and Norilsk deposits. The mineralogy testing is expected to be completed by the end of summer, followed by initial scoping-level metallurgical testing.

Power Metallic Mines (OTCBB:PNPNF)는 Lion Zone 광상의 초기 미네랄로지 결과가 고무적이라고 발표했습니다. IOS Geosciences가 수행한 정밀 현미경 분석에 따르면 구리는 굵은 입자의 황동광(chalcopyrite)과 큐바나이트(cubanite) 내에 존재하며, 이는 전통적인 황화광 집중 방법에 잘 반응할 것으로 보입니다.
연구 결과 PGE 광물은 주로 황동광과 큐바나이트와 연관되어 있어 구리 정광에서 효율적인 회수가 가능할 것으로 예상됩니다. 확인된 PGE 광물에는 스탠노팔라다나이트(stannopalladinite), 프로디트(froodite), 메렌스키트(merenskyite)가 포함되며, 이는 서드버리 분지와 노릴스크 광상에서 발견되는 것과 유사합니다. 미네랄로지 테스트는 여름 말까지 완료될 예정이며, 이후 초기 범위 수준의 야금 테스트가 진행될 예정입니다.

Power Metallic Mines (OTCBB:PNPNF) hat ermutigende vorläufige mineralogische Ergebnisse aus seinem Lion Zone-Vorkommen bekannt gegeben. Die detaillierten mikroskopischen Analysen des Unternehmens, durchgeführt von IOS Geosciences, zeigen, dass Kupfermineralisierung in grobkörniger Chalkopyrit- und Cubanit-Form vorliegt, die gut auf konventionelle Sulfidkonzentrationsmethoden reagieren sollte.
Die Studie zeigt, dass PGE-Minerale hauptsächlich mit Chalkopyrit und Cubanit assoziiert sind, was auf ein Potenzial für eine effiziente Gewinnung im Kupferkonzentrat hinweist. Die identifizierten PGE-Minerale umfassen Stannopalladinit, Froodit und Merenskyit, ähnlich denen, die im Sudbury-Becken und in Norilsk-Lagerstätten gefunden wurden. Die mineralogischen Tests sollen bis Ende des Sommers abgeschlossen sein, gefolgt von ersten metallurgischen Tests auf Scoping-Ebene.
- Preliminary mineralogy results indicate potential for conventional sulphide concentrate recovery methods
- PGE minerals found within or attached to chalcopyrite and cubanite, suggesting good recovery potential
- Mineral species similar to successfully mined deposits in Sudbury basin and Norilsk
- None.
Detailed microscopic scans are being performed on selected mineralized samples from the Lion zone to understand the characteristics of the mineralogy. This will help inform future metallurgical recovery studies on the Lion Zone. Approximately half of the suite of over 100 samples selected to represent the various mineralized zones at Lion have been completed, and results to date are encouraging for potential conventional sulphide concentrate recovery methods.
The Lion deposit has two zones of mineralization defined by drilling, consisting of a High-Grade zone and a lower grade Hanging-wall Zone. Current understanding is that the vast majority of the metal value in the deposit is contained within the High-Grade zone, consisting of semi-massive to massive copper sulphide mineralization.
The scans by IOS reveal the mineralogy of the economic metals, and their host rocks. This characterization is critical for determining potential metallurgical recoveries, in particular for understanding the mineral species of the high value copper and PGEs. Of utmost importance is understanding the characteristics of the High-Grade Zone containing the bulk of the metal in the deposit.
Work to date has shown that the copper mineralization is contained within coarse grained chalcopyrite and cubanite, both which should respond well to conventional sulphide concentration methods, similar to processes carried out on
Additionally, the scans have shown that the majority of PGE mineral species occur within or attached to the chalcopyrite and cubanite (Figure 1). This suggests the potential for very good recovery of these PGEs in a copper concentrate (Figure 2). In addition, the species of PGE minerals including stannopalladinite, froodite, and merenskyite are minerals that are similar to those recovered in other polymetallic ores, such as the
Overall, the character of the mineralization and the host sulphides suggest that good recoveries of both the copper minerals and the PGEs can be expected in conventional sulphide concentration recovery methods.
Mineralogy and Metallurgical Timeline
Mineralogy testing is expected to be complete by the end of summer. Upon completion initial scoping-level metallurgical testing will be started. Aiming to evaluate the optimal recovery method for the deposit. Targeting the start of this work prior to the commencement of the winter drill program, with initial results expected early next year.
