- Chase Mining has received a final report for the review of the Alotta Priority 1 VTEM anomaly within the Lorraine Project
- Southern Geoscience Consulting conducted the review and completed additional plate modelling
- The updated modelling assigns a ‘shallow plate’ to the known near-surface Alotta Ni-Cu-CoPGE mineralised lens which is terminated at about 90m by a porphyry body
- Chase has assessed drilling from 2018 and selected hole ZA-18-01 as suitable to test for mineralisation at depth and to undertake a DHEM survey
- Drilling at Alotta by deepening hole ZA-18-01 is planned to follow the Lorraine drill programme which is currently underway
Chase Mining has received a final report for the review of the Alotta Priority 1 VTEM anomaly within the Lorraine Project.
The company commissioned Southern Geoscience Consulting (SGC) to undertake a peer review of the previously reported plate models associated with its five Priority 1 VTEM anomaly sites and of the Alotta Priority 1 anomaly.
SGC’s primary task was to validate the proposed drill targets at Lorraine before the commencement of a diamond drill program.
SGC has completed the review of the Alotta Priority 1 VTEM anomaly which allows Chase Mining to now select and target one of its 2018 drilled holes, ZA-18-01, for the exploration of massive sulphide targets beneath Alotta.
Contact has already been made with the private landowners within the town of Laverlochere to extend the 2018 access approvals to cover the planned re-drilling and DHEM survey.
In 2018, hole ZA-18-01 was drilled to test for a depth extension to the Alotta massive sulphide lens. It successfully extended mineralisation with an intersection of 4.49m at 1.29% Ni, 3.73% Cu, 0.14% Co and 2.88g/t PGE from 72.28 downhole.
In both the historic drilling and 2018 drilling, the Alotta lens is intruded by feldspar porphyry. On the margins of the massive sulphides, breccia clasts of porphyry are incorporated into the sulphides. Chase interprets this as an indication of later mobilisation of the massive sulphide.
Targeting the ZA-18-01 hole provides the possibility of intersecting massive sulphides at depths of up to 180 metres as well as providing a prime hole for the DHEM survey to test the modelling plates.
Drilling at Alotta is planned to follow the current Lorraine drilling program.
