Pursuit Minerals Limited (ASX: PUR) announced that additional discrete electromagnetic (EM) conductors were identified from secondary moving-loop ground electromagnetic (MLEM) surveys at the Phil’s Hill Target on the Calingiri East exploration licence on the Warrior PGE-Nickel-Copper Project in the western Yilgarn province of Western Australia.
The company reported that highly conductive features (up to 5,093 S/m) were evident on 9 lines of MLEM data over a strike length of ~1,640m.
PUR noted that the conductivity of the Phil’s Hill Prospect is significant and well within the known range of conductivity for the Gonneville PGE-Ni-Cu discovery.
Pursuit said that the Phil’s Hill target is open to the north and south and the Company is considering completing additional MLEM Survey’s to further delineate the prospect for drilling purposes. PUR said that the soil and rock chip assays over Phil’s Hill are expected to be received in the next 2 weeks.
The company said that additional conductors and PGE-Ni-Cu targets at Calingiri East, Wubin & Wubin South, and Calingiri West will be followed up with a second phase of MLEM surveys and ground follow-up programs.
MLEM survey at Warrior project
The company had conducted a detailed airborne EM survey over the Calingiri East, Calingiri West, Wubin, and Wubin South exploration licences on the Warrior PGE-Nickel-Copper Project in February 2021.
Several conductive features identified at “Phil’s Hill” in the Calingiri East survey were then followed up with 2 moving loop ground EM (MLEM) survey. The Infill MLEM program was designed to further refine the orientation and position of the EM anomalies previously identified and provide targets for drill testing.
The company has now reported encouraging results from the secondary moving-loop ground electromagnetic (MLEM) surveys.
Additional discrete highly prospective EM conductors
PUR reported that the MLEM surveys confirmed that the airborne conductors are discrete basement conductors, and all extend into late time. The company said that the modelled conductivities of all anomalies identified were consistent with that expected from PGE-Ni-Cu mineralisation associated with massive sulphides.
Highly conductive features
The company reported that highly conductive features (up to 5,093 S/m) were evident on 9 lines of MLEM data over a strike length of ~1,600 m. PUR said that the modelled depth to top of the conductors was ~100 m and coincident with the edge of an interpreted ultramafic sequence.
Pursuit said that the conductance of the Phil’s Hill Prospect is significant and well within the known range of conductance for the Gonneville PGE-Ni-Cu discovery.
The company said that further MLEM surveys have now refined the interpreted EM plates and have identified 4 discrete EM responses and increased both the conductivity and strike length. These EM responses have not been closed off to either the south or north by MLEM surveys.
PUR announced that based on the EM response, Phil’s Hill represents a high-priority drill target.
Updates and next steps
The Company said that an Aboriginal Heritage Agreement has been executed and the Company continues to expedite planning for drill testing to commence within 6-8 weeks.
Pursuit said that the drilling program is only contingent on Aboriginal Cultural Heritage requirements being met and confirmation of the lodged Program of Work (POW) being accepted by the Department of Mines, Industry Regulation and Safety.
PUR reported that it has completed geochemical soil sampling over Phil’s Hill and anticipates results within the next 2 weeks.
The company reported that additional follow-up areas of interest indicated at Calingiri West and Wubin, are awaiting post processing due to shallow conductive cover in these areas. PUR said that the results from the post processing of AEM data will drive further on ground exploration programs at Calingiri West, Calingiri East, Wubin, and Wubin South.
Pursuit noted that ground follow-up of targets identified from the full AEM and aeromagnetic data may entail additional ground EM surveys and/or soil geochemical surveys.
“The Company is extremely encouraged by the additional conductors at Phil’s Hill Prospect”
Pursuit Managing Chief Executive Officer, Mark Freeman, said: “The Company is extremely encouraged by the additional conductors at Phil’s Hill Prospect; the MLEM program has extended and refined our drill targets.
The Phil’s Hill target is now over 1,600m in strike length, located in a highly prospective position on the margin of an interpreted mafic-ultramafic intrusion, where PGE-Ni-Cu mineralisation often concentrates, and is ready for drilling, subject to government and heritage approvals.”
