Encouraging Magnetic Survey Results at Tyr Property in Australia
VANCOUVER, BC, Aug. 30, 2022 /PRNewswire/ - Megawatt Lithium and Battery Metals Corp. (CSE:MEGA) (FSE: WR20) (OTCQB: WALRF) (the " Company" or "Megawatt") has received the final results report from the drone magnetic survey at its Tyr Project in New South Wales, Australia (Figure One). The tenement covers 100 units over an area of 299 km2.
A drone magnetics survey was completed by independent contractor AirGeoX in mid-July 2022 over an area covering the old Burra and Torny Silver workings. The survey totalled 123-line km was flown at a height of 35m over a 20m-by-20m grid pattern.
Mapping and rock chip sampling over the survey area prior to the magnetics survey showed geochemical dispersion on the surface associated with base metal mineralisation in and around both of the old silver workings.
The base metal mineralisation is polymetallic in nature and the mineralisation is formed in multiple vein arrays believed to be mostly parallel to sub-parallel to the main controlling structure at each specific location.
The predominantly silver lead zinc base metal mineralisation is believed to be structurally controlled and associated with three main structures whose orientations are NW, SE and EW. It has been postulated that at the intersection of at least two, and sometimes all three of these structures, a loci were formed for the accumulation of significant mineralisation.
Highlights of Megawatt's 2020 and 2021 sampling programs of for both the Torny and Burra Prospects include the following assay results:
- 504g/t Silver,
0.22% Cu,6.44% Pb and9.57% Zn, 8220 ppm Sb – grab sample - 389g/t Silver,
0.63% Cu,2.64% Pb and10.95% Zn – grab sample - 355g/t Silver,
0.04% Cu,1.70% Pb and0.14% Zn – grab sample - 43g/t Silver,
0.04% Cu,1.22% Pb and12.45% Zn -Burra adit
The Torny Prospect has minor copper mineralisation associated with the silver-lead-zinc as well as significant antimony (Sb).
The Burra Prospect has higher copper and zinc than Torny but less lead and negligible antimony.
The data used in the above sample results were derived from recent grab sampling of old workings where both mineralised looking and non-mineralised looking material were selected based on the overall degree of representation of each type of material on the old dumps.
Mapping of the area suggested that the surface expression of these structures could not previously be traced continuously between old workings and were possibly masked by surface erosional features and that therefore a method was required to test the continuity of these structures, and potential base metal mineralisation, subsurface.
Historical records from the old workings across the Tyr Project Area mentioned the close association of large bodies of pyrrhotite juxtaposed with the base metal mineralisation. Large blocks of pyrrhotite weighing several kg have been found in recent field work around the shafts of the old workings within the Tyr Project.
Pyrrhotite, an iron sulphide mineral (FeS2), is magnetic in nature and a magnetics survey was planned in order to delineate how much pyrrhotite exists sub surface and therefore giving an indication of the potential base metal mineralisation associated with the pyrrhotite.
The results of the survey are shown below in Figure Three which is the Total Magnetic Image (TMI) Reduced to Pole (RTP) processed from the data collected by the drone survey.
Target Areas 1 and 2 incorporate the old Torny and Burra silver workings with Target Area 3 likely to extend in a north easterly direction beyond the survey area. Target Areas 2 and 3 appear to follow NW trending structures whilst Target Area 1 appears to align with an EW structure.
These three target areas will now form the basis of a confirmatory/exploratory drilling programme designed to intersect potential base metal mineralisation spatially associated with the magnetic highs in each of the target areas believed to be significant accumulations of pyrrhotite.
Target Areas 1 and 2 have been mapped and sampled on the surface due to their proximity to the old Burra and Torny silver workings respectively, however, Target Area 3 will need mapping and sampling on the surface both within the survey area and extending out in a north easterly direction.
Mapping of the Tyr Project Area has shown that the host for mineralisation are metasediments, mainly silicified siltstones, that have a subvertical to vertical dip (75o to 90o) that varies along main structures from steeply easterly dipping through vertical dipping to steeply westerly dipping.
The next stage for the evaluation of the target areas from the Tyr Magnetics Survey are:
- Complete mapping and sampling on the surface coincident with Target Area 3 in order to derive structural and orientation data to be used in drillhole planning.
- Design drilling programme to intersect base metal mineralisation spatially associated with the magnetic highs in the 3 Target Areas believed to represent accumulations of pyrrhotite.
Megawatt is also now currently reviewing the suitability of utilising magnetics and/or radiometrics surveys over its other Australian exploration tenements.
