Havilah Resources has reported that final laboratory assays have now been received for reverse circulation (RC) drill samples from the recent Grants Iron Ore Basin drilling.

According to the results, an improvement by an average of approximately 18 per cent in the laboratory iron assays compared to the preliminary handheld Niton XRF iron analyses has bee recorded.
This drilling is part of a comprehensive program of work currently being performed and funded by SIMEC Mining as part of their due diligence investigation of the commercialisation potential of Havilah’s Maldorky and Grants iron ore projects. The drilling program was implemented and supervised by Havilah personnel.
The reported laboratory assay intervals above indicate average grades in the order of 24-27 per cent Fe.
Diamond drilling is also currently underway to provide early sample material for preliminary metallurgical testwork. The diamond drilling is being carried out by MJ Drilling using a multipurpose UDR650 drilling rig. The HQ3 sized diamond core hole is using the existing RC hole GBRC006 (that was halted early at 130 metres depth due to air circulation issues) as a precollar to extend beyond the base of the iron bearing sequence (estimated to be >500 metres depth). This hole is intended to provide the first complete intersection of the Grants Basin iron bearing sequence and will also provide partial twinned hole drill data for the adjacent GBRC008 (316 metres total depth).
Commenting on the drilling results, Havilah’s Technical Director, Dr Chris Giles said, “The recently received laboratory assays, as expected, are higher than the Niton hand-held XRF analyses that were previously reported. “This, combined with the exceptionally thick iron ore intersections, confirms a major iron ore discovery in the Grants Basin.
“One thing we do not yet know is the thickness of the iron formation in the central part of the Grants Basin, which the present diamond drillhole should tell us.
“The drillcore samples will be used by SIMEC Mining to carry out initial metallurgical work and to compare this iron ore with that from the JORC status Maldorky and Grants iron ore deposits. “This was a well-planned and well executed drilling program that has achieved great success, and I thank all concerned including SIMEC Mining for their funding support”, he said.
