Norfolk Metals continues to explore its Orroroo uranium project in South Australia along with streamlining exploration at its Roger River copper project in Tasmania.

The company has secured a geophysics contractor for the gravity survey at Orroroo with the intent to delineate paleo channels potentially hosting roll front uranium style mineralisation.

Norfolk Metals (ASX:NFL) has also received final assays from Roger River, confirming four acid digests of 50g samples is the preferred method for basalt host rock containing coarse disseminated native copper – based on cost and time frames.

“We remain excited to progress both of our projects with additional geophysical and/or geochemistry work prior to subsequent drilling,” executive chairman Ben Phillips said.

Roll front uranium potential at Orroroo

Norfolk recently completed the downhole geophysical survey at Orroroo which confirmed uranium occurrences in all three target zones (wells) of which the depths are potentially suitable for proven in-situ mining.

It also flagged peak uranium at 650ppm pU3O8 within an interval of 192ppm pU3O8 over 0.5m from 112.59m via PFN in well 7P3.

Plus, uranium recorded from the survey supports the company’s proposed “oxidized tails or interface zones” of roll-front uranium style mineralisation theory.

The aim for the upcoming gravity survey is to delineate the paleo channels in the Walloway Basin – which will assist with planning for the maiden drill program.

“The Orroroo program is not expected to be technically challenging as we progress, after our down hole survey successfully defined uranium in all historical wells tested; the program should be considered as more of a procedural process ensuring all stakeholders are considered and skilled contractors are utilised to conduct geophysics and subsequently drill preparations,” Phillips said.

Native copper the key at Roger River

Norfolk says geochemical analysis on its recent drilling at Roger River proved that sieving every sample was laborious and costly, so for practicality and cost effectiveness, the plan going forwards is for future drilling where native copper has been observed in the core.

The ME-ICP44 using 50g sample mass will be implemented as standard practice, and depending on the native copper sections observed in the drill core, the company intends to send selected samples for copper screening analysis.

“On Roger River, Norfolk has established the preferred assay technique for host rocks displaying native copper with any future drilling expected to have shorter turnaround times for assays,” Phillips said.

Potential acquisitions on the radar

Phillips also flagged that the company is currently reviewing potential projects, investments and acquisitions.

“It should also be noted due to the company’s capital structure and healthy balance sheet, opportunities for project acquisitions have been quite forthcoming in recent months,” he said.
