Gold exploration and development company, Ora Banda Mining Ltd (ASX: OBM) engaged in high-impact exploration & mine planning at its expansive land tenure in the highly prospective region of Eastern Goldfields in Western Australia, has announced further set of high-grade assay results from its Callion Resource Definition Drilling Programs.
Callion Resource Definition Drilling Programs
The primary objective of the drilling at Callion has been extension and upgradation of the current open pit Resource and delineating a maiden underground Resource. Ora Banda has concluded Phase 1 and Phase 2 at Callion with a total 53 RC (reverse circulation) holes (6,938 m) and 17 diamond tails (1,948 m) completed.
Underground Target Results returned include:
- 8.0m @ 20.2 g/t from 118m
- 8.0m @ 16.4 g/t from 139m
- 10.0m @ 3.5 g/t from 158m
- 1.4m @ 16.9 g/t from 179m, including 1.0m @ 22.6g/t
- 2.6m @ 8.35g/t from 183m
- 2.0m @ 9.68g/t from 124m
Open Pit target results returned include:
- 2.0m @ 6.95 g/t from 109m
- 7.0m @ 1.7 g/t from 102m, including 3.0m @ 3.34g/t
These results build on those announced on 28 January 2020 including -
Underground target results as:
- 4.8m @ 34.4 g/t from 232m, including 0.3m @ 498.2g/t
- 1.2m @ 15.7 g/t from 220m
Open Pit target results include:
- 10.0m @ 8.0 g/t from 76m
- 5.0m @ 3.3 g/t from 73m
The hole CNRC19032 that returned 8.0m @ 16.4g/t from 139 metres was particularly significant in this batch of results from the underground diamond drilling program as it targeted and successfully intersected the along strike continuation of the high-grade shoot associated with the historical main underground mining area. The hole will remain a key focus for further exploration activities.
Ora Banda has also outlined a conceptual development plan for the Callion deposit. The plan comprises an open pit cut back for re-building the underground access, rehabilitation of existing underground mine development where required to extract a number of high-grade zones that remain within the upper sections of the historical mine. After that, the company will focus on developing and extracting new high-grade regions below the existing mine workings.
David Quinlivan, Ora Banda Managing Director commented that the receipt of results from Callion would enable Ora Banda to move forward with the advancement of the Mineral Resource update for this deposit, with a high-grade nature that continues to shine through.
About the Callion Deposit
Callion is one of the priority targets located 13 km South West of the Davyhurst Processing Plant in Eastern Goldfields. Historically, different operators inlcuding Western Mining Corporation (1934-1959), Callion JV (late 1990s) and Croesus (2004-2005) undertook mining development activities at Callion.
Currently, the Callion open-pit encompasses ~650 m long to ~40 m deep, with the underground workings stretch till the southern end of the pit at a vertical depth of around 220 m below the surface. The total historic production noted as 135Kt at 4.1g/t grade for 17.6koz for open pit and underground mine delivering 146Kt at 15.8g/t grade for 74Koz for a total output of 280Kt at 10.2 g/t grade for contained gold 91,650 ounces.
