Godolphin Resources has received assay results for four diamond drill holes from a 285.6 metre drilling program conducted in July-August 2022 at its Narraburra rare earth element and rare metals project, 12 kilometres northeast of Temora in central west NSW.
Broad intersections of rare earth element mineralisation were found in all four diamond holes, in both weathered surficial material and in underlying fresh rock.
Intercepts within the extent of previously identified mineralisation were:
- 72.3 metres at 687 ppm total rare earth oxides (TREO) from 27 metres, including 19 metres at 528 ppm TREO from 27 metres (weathered zone); 10 metres at 1027 ppm TREO from 46 metres (weathered zone); and 43 metres at 679 ppm TREO from 56 metres (fresh rock zone).
- 14 metres at 648 ppm TREO from 34 metres, including 5 metres at 671 ppm TREO from 34 metres (weathered zone); and 9 metres at 635 ppm TREO from 39 metres (fresh rock zone).
Intercepts outside the extent of previously identified mineralisation include:
- 17 metres at 508 ppm TREO from 34 metres (weathered zone); and
- 14 metres at 525 ppm TREO from 35 metres (weathered zone).
All drill holes intersected significant rare earth element/rare metal mineralisation, with assay results confirming previous historical exploration activities.
Higher levels of TREO in shallower weathered rock zones provide potential for cost-effective near-term extraction opportunities.
Planning is underway for mineralogical and metallurgical testing to determine the optimum extraction pathways for both weathered surficial mineralisation and the weathered rock material.
Pending results from a 27-hole diamond core drill program completed in October will provide additional insight and sufficient data to complete an updated JORC 2012 Mineral Resource.
Godolphin managing director Jeneta Owens said the results from the initial four-ho0le drill program at Narraburra were highly encouraging.
Owens continued: “The drill results confirm the presence of the mineralisation as defined by previous explorers, which was the first step for Godolphin.
“Following a comprehensive review of the assay results, the company has gained a much better understanding of Narraburra’s geology.
“Sufficient samples have been obtained to commence early-stage mineralogical and metallurgical testing.
“The Company has also submitted all diamond drill cores from the recently completed 27 diamond drill hole Phase 2 program.
“We now have a total of 31 diamond drill holes and the results from which can be used to upgrade the Project’s existing Mineral Resource Estimate to JORC (2012) standards.
“Our drilling has shown that there is substantial weathered surficial REE/RM mineralisation.
“This opens up more processing options and also potentially lower cost mining methods.
“As soon as possible we will commence metallurgical test work to start defining the best ways to process the Naraburra REE/RM mineralisation.”
