Northern Minerals Ltd (ASX:NTU) continues to be encouraged by results from drilling at Dazzler deposit with heavy rare earth grades consistently higher than average grades at the Browns Range Project in the East Kimberley region of WA.
Best results from Dazzler include 15 metres at 2.72% total rare earth oxides (TREO) from 20 metres and 34 metres at 1.55% TREO from 25 metres while anomalous results from Dazzler Northwest warrant follow-up.
All assays have been received from mineral resource infill and step-out reverse circulation (RC) drilling completed at Dazzler in September and November 2019 with other results including 15 metres at 2.72% from 20 metres and 11 metres at 2.21% from 1-metre.
“Adding mine life to the project”
Managing director and CEO George Bauk said: “The exploration program is an important component of the overall strength of the Browns Range Heavy Rare Earth Project.
“As well as assessing the technical and economic feasibility of the larger-scale project through production from the pilot plant, the exploration program is important in adding mine life to the project.”
Additional mineralised zones were also included in the area between Dazzler and Iceman with results including:
- 14 metres at 1.8% TREO from 13 metres;
- 26 metres at 0.87% from 17 metres;
- 5 metres at 1.60% from 27 metres; and
- 12 metres at 1.13% from 23 metres.
Drilling in the Dazzler and Iceman area has indicated a mineralised trend of over 1-kilometre, with further untested potential along strike to the northwest and southeast.
High-grade mineralisation has been extended west of the Gambit West pit while broad mineralisation was encountered at Banshee South, including 22 metres at 0.52% TREO.
Results incorporated into geological model
All new drill results have been incorporated into a revised geological model and an updated mineral resource estimate, which is expected to be announced towards the end of the March quarter.
The current inferred mineral resource is 144,000 tonnes at 2.23% TREO comprising 3.2 million kilograms of TREO.
Three geotechnical diamond drill holes and two more metallurgical drill holes were also completed at Dazzler in late 2019-early 2020.
Core from the two PQ diameter diamond drill holes will be used as metallurgical samples for further test work at Nagrom under Northern Minerals supervision.
The geotechnical drill holes will provide data for pit design and geotechnical studies.
