Drilling Program Completed at Mallina
Brisbane, July 17, 2017 AEST (ABN Newswire) - Sayona Mining Limited (
ASX:SYA) (DMNXF:OTCMKTS) ("Sayona" or the "Company") is pleased to report an exploration update at its Mallina spodumene pegmatite project in the Pilgangoora district of Western Australia.
Highlights
- 18 holes totalling 1,343m completed in the first phase of drilling at Mallina
- Five spodumene pegmatites targeted with pegmatite intersected in each area
- Assay results return anomalous lithium with up to 5m @ 1.00% Li2O from 46m in hole SMRC012 and with a peak assay value of 1.62% Li2O over one metre from 27m in hole SMRC005
A total of 18 reverse circulation drill holes for a total 1,343 metres have been completed, testing five spodumene pegmatites.
At each target drilling has intersected pegmatite. The eastern group of pegmatites (see figures in the link below) returned the broadest zones of pegmatite, with up to 19 metres downhole width (recorded in SMRC001). The pegmatites have been variably altered by silicification, which results in zones of green, fine grained silica rich replacement pegmatite.
Spodumene, observed during logging, has good correlation with assay results (see Table 1 in the link below). Intercepts include up to 5m @ 1.00% Li2O from 46 metres in hole SMRC012 and a peak assay result of 1.62% Li2O from 27 metres to 28 metres in hole SMRC005. The drilling results are disappointing as they do not correspond with the surface rock sampling results, which returned mineralisation across the full width of surface pegmatite.
The timing of the silicification event, which appears to have led to the replacement of spodumene with silica is unclear. Similar late stage magmatic silicification events however are described in other pegmatite systems worldwide. Drilling has tested fresh bedrock and surface weathering does not appear to have caused the effects.
Petrology and other studies are being carried out to understand the drill results further. A zonation may be identified and areas with potential for preserved spodumene, or targets where the remobilised lithium has migrated to may be identified. Also, additional prospective pegmatite systems which remain untested may be highlighted. On completion targets can be considered for further drill testing.
