Excellent manganese drilling results at Red Lake Prospect, Earaheedy Project.
• High grade manganese oxide drill intersections at shallow depth at Red Lake Prospect
• These are the first potential DSO manganese drill intersections reported in the Earaheedy Basin
• Significant intersections include:
ZRLRC013a, 5 metres @ 34.8% Mn from 22 metres
including 3 metres @ 41% Mn
ZRLRC021, 3 metres @ 31.6 % Mn from 6 metres
ZRLRC024, 3 metres @ 30.7% Mn from 3 metres
including 1 metre at 40.2% Mn
• Drilling results confirm Zenith’s exploration model and Kalahari style stratabound manganese setting
• Potential for target stratigraphy to extend 3 kilometres to the east
• Planning for further drilling under way
Earaheedy manganese project
In 2010 Zenith identified the western Earaheedy Basin as a potential new manganese province with similarities to the giant Kalahari manganese field in South Africa.
Primary mineralisation is stratiform manganese carbonate and is associated with iron formations in adjacent stratigraphy. This primary mineralisation is a future target for exploration for large tonnage manganese deposits.
Zenith’s priority target is high grade supergene manganese oxide formed by weathering of the primary carbonate and grading >40% Mn.
As first mover Zenith established a strong land position with tenements covering 75 strike kilometres of prospective stratigraphy.
Zenith has completed two successful drilling programs for manganese in the Earaheedy Basin since making the original discovery of stratabound manganese at the Lockeridge Prospect
At the Lockeridge prospect, drilling intersections of carbonate mineralisation included (ASX 25 Oct 2010):
12m @ 11.1% Mn from 28m
3m @ 18.0% Mn from 37m
3m @ 13.0% Mn from 14m
At the Black and Blue prospect, drilling intersections of oxide mineralisation included (ASX 16 Dec 2011):
31 m @ 7.9% Mn, including 1m @ 22% Mn and 3m @ 14.3 %Mn
Test work on low cost beneficiation is planned for Black and Blue, while the new intersections from the Red Lake prospect show potential for direct shipping manganese ore.
