Iltani Resources Limited (ASX: ILT) has announced that recently received historical metallurgical test work results for its Orient project, Queensland, have confirmed the potential to produce high quality lead-silver and zinc-indium-silver concentrates.
Robertson Research Australia Pty Ltd carried out metallurgical test work on core samples from the Orient West deposit in 1988. Test work confirmed that it is viable to produce two separate high-quality concentrates, a lead-silver concentrate grading approximately 48% Pb and 2,250g/t Ag, and a zinc-indium-silver concentrate grading 47-48% Zn, 2,000g/t In, and 200g/t Ag.
Managing director, Donald Garner, commented, “Iltani has recently received a large package of historical data including drill logs, assays results, and technical studies (mine design, feasibility studies, and metallurgical test work) for a number of projects in the Herberton region. The bulk of the data relates to Iltani’s Orient and Isabel projects, and dates from the 1970s to 1980s. This data enables Iltani to accelerate work in a much more focused and cost effective manner on these projects.”
Based on enquiries to date, Iltani believes that both concentrates will be able to be sold, and the following elements (silver, indium, lead, and zinc) can be included in a metal equivalent calculation, having a reasonable potential to be recovered and sold.
Additionally, the company has highlighted that Indium is defined as a critical raw material by multiple studies, driven by its strategic end uses and potentially constrained supply.
The company is now able to restate recent Orient drilling results on a silver equivalent (Ag Eq.) grade basis. Iltani’s recently completed Stage One RC drilling programme highlights this potential, with positive drill intercepts at both Orient West and Orient East. Notable intercepts include:
- Orient West: ORR010: 41m @125.3g/t Ag Eq. from 60m downhole
and ORR013: 41m @71.4g/t Ag Eq. from 55m downhole
- Orient East: ORR001: 38m @190.0g/t Ag Eq. from 19m downhole
and ORR003: 41m @107.2g/t Ag Eq. from 39m downhole
The company will shortly commence a Stage Two drilling campaign, seeking to extend mineralization drilled in Stage One and test multiple high priority stockwork targets.
