MNM has been granted exploration licenses for the tenements EL26018, EL26019, EL26020 and EL26021. These are common with historic tenements AP2161 and AP1766. The overlap can be seen in the graphic below.
The results of the historic tests are:
Company name IMC
Year 1969
Tenement AP 1766,2159,2160,2161,1897
Author Perrino FA
Report no CR1969-0022
Project area Alexandria region
No of drillholes 98
Mapsheet RANKEN, MOUNT DRUMMOND, BRUNETTE DOWNS, WALHALLOW, CALVERT HILLS
Drilled logs Yes
Assay Yes
Formation Wonarah Formation, Anthony Lagoon beds
Phosphate lithology Siltstone, chert , carbonate rocks (limestone, dolostone) and mudstone
Significant holes More than 20% P2O5 found in W2, W20, W37
Comments Report proved that distribution of phosphatic material is greater around margins of Precambrian basement and over
probable basement highs. Drilling in the Wonarah authority proved the presence of ore-grade phosphate.
Company name IMC
Year 1969
Tenement AP 2161
Author –
Report no CR1970-0040
Project area Alexandria region (Wonarah)
No of drillholes 139
Mapsheet RANKEN, BRUNETTE DOWNS
Drilled logs Yes
Assay Yes
Formation Wonarah Formation
Phosphate lithology Cherty siltstone, siltstone, mudstone
Significant holes W39, W48, W60A,W66, W73, W112, W103, W117, W119, W135 have more than 20% P2O5.
Comments Several holes showed a positive result for phosphate; 10 holes contained >20% phosphate. An interpretation of the data
is in Perrino (1969).
Company name IMC
Year 1970
Tenement AP 1766
Author –
Report no CR1970-0037
Project area Alexandria region
No of drillholes 88
Mapsheet RANKEN, MOUNT DRUMMOND
Drilled logs 44 provided
Assay Provided for some holes
Formation Burton beds (now Wonarah Formation)
Phosphate lithology Siltstone, clayey siltstone, chert, limestone
Significant holes Phosphate percentages more then 15% were recorded in A76, A79 and A80
Comments Several holes contain <10% P2O5 and three holes contain >15% P2O5. Lithological and gamma logs of 44 holes are provided. It also includes two structure maps of region.
I have had a look at the actually drilling report from IMC showing drill hole locations, drill depths and results. I haven't had the time to post any image overlays yet.
In summary, it confirms that the tenements are largely unexplored, the drilling was shallow mostly 30-60m in depth. Most P2O5 was found to start around the 50m mark.
EL26018 showed the most promise with drills in the NE and SE corners returning 10%+, which is on the border between EL26018 and EL26019, however the centre of either tenement has not been drilled. This is because it was a scout drilling program that was restricted by existing access at the time.
Only 4 holes drilled in EL26020 in the NE corner turned up nothing, probably because they didn't go deep enough only 35m maximum. Probably is something here a bit deeper.
Plenty of exploring to do before we see the full picture here otherwise the MC would be the same MAK already. Having said that all indicators point to some sort of resource,we just don't know how big or what quality, that is why MNM is developing a systematic study and drilling program for the area, which we should hear details about very shortly.
