Adavale Resources Limited (ASX: ADD) has received positive preliminary assay results from two recently completed diamond drillholes at the Luhuma Central Prospect within Prospecting Licence PL 23980/2023 in Tanzania.
The two drillholes were designed to test a new Audio-magnetotelluric (AMT) anomaly.
These preliminary assay results for the initial drilling at Luhuma Central have confirmed the presence of nickel bearing sulphide intersections in our first two completed drillholes,” Executive Director, David Riekie, said.
“These results are extremely encouraging as we continue to drill and seek to unlock the strike potential of this mineralisation, based on our extensive AMT, soil and EM datasets covering this area.
“We have cased the Luhuma Central diamond holes and will soon commence the Downhole Electromagnetic (DHEM) surveys on each hole to assist with this ongoing drilling programme. DHEM is a critical tool to effectively drill the interpreted one to 1.5km extension.”
Drilling Programme
Adavale has recently undertaken diamond drilling on Prospecting Licence, PL 23980/2023 (referred to as Luhuma Central), as part of a 5,000m combined DD and RC drill programme to test a series of targets generated by the company on the Luhuma Trend, a historically recognised zone of strongly elevated gravity and electromagnetic anomalism.
The drillholes DDLUHC001 and DDLUHC002 intersected 4.13m of massive sulphides and 4.90m of blebby and heavily disseminated sulphides respectively. If mineralised intersections are connected between the drillholes as they are interpreted to be, then these sulphide bearing intervals would approximate their true thickness (although the drillholes are not completely orthogonal to the dip). These sulphides are coincident with a strong discrete AMT anomaly that can be traced to the north and south on AMT lines L1, L2 and L3.
Drilling of hole DDLUHC003 is in progress and is located ~60m to the north of the two assayed holes as shown on the plan view of Luhuma Central. This new hole is expected to be completed this week.
Additional step-out drilling to further test the AMT anomaly to the north and south are shown as the planned holes.
Next Steps
The company currently has two drill rigs on site at Kabanga Jirani, with one rig focused on Luhuma Central and the other currently drilling high priority targets at HEM 2. Each rig will be drilling a hole every seven to 10 days.
Included in the upcoming activitie will be the following:
- Visual interpretation of new holes, as appropriate;
- Aqua regia and full acid digest assay results
- Downhole EM results
