Slide 4: Regional Geological Setting
Regional Geological Setting For personal use only The Thackaringa Cobalt Project is located within the Broken Hill Domain of the southern Curnamona Province The project area covers portions of the Broken Hill and Thackaringa group successions 4
Slide 5: Regional Geological Setting
Regional Geological Setting For personal use only The mineral deposits (Pyrite Hill, Big Hill and Railway) are characterised by large tonnage cobaltiferous pyrite mineralisation hosted within siliceous albitic gneisses and schists of the Himalaya Formation The mineralisation is concordant with r

Slide 7: Exploration Targeting Elements
Exploration Targeting Elements For personal use only Stratigraphic affinity Himalaya Formation of the upper Thackaringa Group Surface geochemistry Gossan (high Fe cobalt depleted) vs. pyritic gneiss High mobility of cobalt in iron-rich, oxidising environment – no notable Fe scavenging G
Slide 8: Mineralisation Style
Mineralisation Style For personal use only Multiple styles of pyrite mineralisation; dominantly medium – coarse grained disseminations with semi-massive to massive zones Minor pyrrhotite – no other notable sulphides Strong correlation between sulphur (pyrite) and cobalt Two key structural co
Slide 9: Ore Mineralogy
Ore Mineralogy For personal use only Ore composition averages 10 - 35% sulphides (almost exclusively pyrite), 25 - 45% quartz, 25 - 55% albite (sodium feldspar) & minor amounts of micas, clays and iron minerals Cobalt is substituted into the pyrite mineral lattice - no other discrete cobalt mine

Slide 11: Pyrite Hill Deposit
Pyrite Hill Deposit For personal use only The Pyrite Hill deposit extends over 1.2km along strike, approximately 300m down dip and varies in thickness from 10 to 100m Mineralisation is hosted by quartz-albite gneiss with both the hanging wall and footwall comprised of quartz-albite- biotite gnei
Slide 12: Pyrite Hill Deposit
Pyrite Hill Deposit For personal use only The northern-western extent of the deposit is generally undeformed and dips at approximately 50° to the northeast In the central part of the deposit, rapid thickening of mineralisation, resultant of near isoclinal folding, occurs in correlation with a ge
Slide 13: Railway Deposit
Railway Deposit For personal use only The Railway deposit is considered a north-eastern extension of the Big Hill deposit with continuous mineralisation observed over some 2.5km The southern extent of the deposit is generally linear with an average thickness of 30m increasing to approximately 60
Slide 14: Railway Deposit
Railway Deposit For personal use only The central part of the deposit is characterised by extensive ductile deformation and complex folding resulting in a rapid thickening of mineralisation up to 300m At the northern-eastern extent, the mineralisation is increasingly discontinuous, comprising a
Slide 15: Oxidation Profile
Oxidation Profile For personal use only Shallow oxidation profile characterised by variable zones of sulphide mineralisation intercalated with localised oxidation and partial sulphide/cobalt depletion 2018 – 19 drilling improved definition of oxidation boundaries. Significant, shallow intersecti
