Eclipse Metals Ltd (ASX:EPM) has intersected manganese mineralisation in all holes of a second phase diamond drilling program at Amamoor prospect within Mary Valley Manganese Project in Queensland.

Strong manganese mineralisation was identified in all drill holes hosted in strongly brecciated/sheared, fractured altered metasediment units.

The program comprised six diamond drill holes for 97.6 metres in the Northern, Central and Southern areas although difficult drilling conditions were encountered.

Drill-tested for the first time

Eclipse Metals executive chairman Carl Popal said: “The successful delineation of further shallow manganese mineralisation has increased our understanding of the geological controls.

"We have drill-tested areas for the first time such as the Northern and South/Central prospects with great success as the extent of manganese mineralisation in these locations was unknown.”

The drilling program tested for extensions of previously drilled high-grade manganese mineralisation along 160 metres of strike and down dip to 20 metres.

All holes were planned to a final depth of 20 metres but due to difficult ground conditions, some holes were terminated at shallower depths.

Assays expected

Half-core samples from prospective and mineralised zones from all the drill-holes have been cut and sent to a laboratory in Brisbane for assaying with most intervals to be assayed on a per metre basis.

Popal said: "We look forward to receiving assay data from the laboratory in Brisbane.”

Manganese mineralisation is hosted within well-defined brecciated shear zones, open along strike in both directions and down dip.

Future exploration

Based on positive results from the 2018 program and success in recent drilling, it is clear that further ground access is required to adequately explore and assess the economic potential of the Amamoor manganese deposits.

Several nearby historical workings are yet to be tested and production of a bulk sample will be required for potential consumers.

Eclipse has started planning for further ground access, definitive geophysical surveys, drilling and bulk sampling.
