Great Northern Minerals Announces Promising Pegmatite Discoveries at Sukula Project
GREAT NORTHERN MINERALS LIMITED (GNM) Share Update September 2024 Monday 23rd
Great Northern Minerals Defines Extensive Pegmatite Swarm at Sukula Project
Great Northern Minerals Limited (ASX: GNM) has announced promising results from their recent exploration at the Haapaniemi prospect, part of their 100%-owned Sukula Project in Finland. The discovery of a highly fractionated pegmatite swarm over an extensive area highlights the potential for significant lithium mineralization.
Instant Summary:
- Newly defined swarm of highly fractionated pegmatite dykes over a 600m² area at Haapaniemi prospect.
- Core zonation of pegmatites offers promising drill targets with potential spodumene zones at depth.
- Portable XRF measurements revealed high rubidium levels up to 5,562 ppm.
- Assays returned up to 538 ppm Li2O, 256 ppm Ta2O5, and 118 ppm Cs2O.
- GNM to consider various geochemical and geophysical methods to progress towards a drill-ready target.
Exploration Results
Great Northern Minerals Limited (GNM) has announced the discovery of a highly fractionated pegmatite swarm over a 600m² area at the Haapaniemi prospect, part of their Sukula Project in Finland. This discovery is significant as it suggests the presence of lithium-rich pegmatites, which are crucial for lithium extraction.
The Haapaniemi prospect is located 8km northwest of United Lithium's Kietyonmaki spodumene pegmatite deposit. The area shares similar geological characteristics with the Kaustinen Lithium Province, known for its rich lithium deposits.
Geochemical Findings
During the recent field survey, GNM's consultants identified a swarm of fractionated pegmatite dykes. Portable XRF measurements on microcline revealed high rubidium levels, indicating highly fertile pegmatites. Assays returned up to 538 ppm Li2O, 256 ppm Ta2O5, and 118 ppm Cs2O, with a K/Rb ratio as low as 12, supporting a high degree of fractionation.
Potential for Lithium Discovery
The core zonation of pegmatites at Haapaniemi offers a promising drill target. The geochemical data suggests a zonation from primitive to highly evolved pegmatites, potentially bearing spodumene at depth. This makes Haapaniemi a highly prospective area for further exploration and drilling.
GNM plans to employ various geochemical and geophysical methods to progress the Haapaniemi prospect towards a drill-ready target. The company is optimistic about the potential for a significant lithium discovery within the Somero lithium province.
The discovery of highly fractionated pegmatites at Haapaniemi is a positive development for Great Northern Minerals. The high rubidium levels and promising assay results indicate the potential for significant lithium mineralization, which could boost investor confidence and positively impact the company's stock price. The planned geochemical and geophysical methods to further explore the area will be crucial in determining the full potential of this discovery.
Investor Reaction:
Analysts are likely to react positively to this announcement, given the promising assay results and the potential for significant lithium mineralization. The proximity to United Lithium's Kietyonmaki deposit adds further credibility to the prospect. Investors will be keen to see the results of the planned geochemical and geophysical methods and the subsequent drilling program.
Conclusion:
Investors should keep a close eye on Great Northern Minerals as they progress their exploration at the Haapaniemi prospect. The promising results from the recent field survey indicate the potential for a significant lithium discovery, which could have a positive impact on the company's stock price. Stay tuned for further updates as GNM advances towards a drill-ready target.
