The underling geology at Panama is Ordovician-Silurian Mathinna Group sediments that have been intruded by Devonian granodiorite, the Lisle Granodiorite. The Mathinna Group sediments consist of psammitic siltstone-sandstone sequences with minor graphitic slate. The Mathinna Group has been deformed by the Devonian Tabberabberan Orogeny, forming northwest-southeast trending asymmetric folds with a moderately developed axial planar slatey cleavage.
The Great Pyramid deposit is located around a topographical feature known as Pyramid Hill and is hosted by Mathinna Group sandstones. The deposit is currently known over a strike length of more than 500 metres with an average width of approximately 150 metres. The depth extent of the deposit is not known with relatively minor deeper drilling having encountered mineralisation to depths of approximately 300m below surface.
The Aberfoyle project area straddles the boundary between the Silurian to Devonian Mathinna Supergroup sedimentary rocks and the Devonian Ben Lomond Granite. The historic Aberfoyle (tin) and Storeys Creek (tin-tungsten) mines as well as other vein systems are hosted in the sedimentary rocks and occur as strike extensive systems of sheeted and stockwork veining.
The New England Orogen (NEO) of New South Wales is host to thousands of historic tin workings in the form of placer, lead and deep lead deposits mined in the late 1800s. The Emmaville-Torrington and Tingha districts host the New England’s significant tin deposits, including Taronga Tin deposit which contains a JORC 2012 Indicated and Inferred Mineral Resource estimate of 36.3Mt at 0.16% Sn for 57,200 tonnes of contained tin (Source: AusTin Mining Limited).
The Teviot East and Nevis River Projects are situated on interpreted major deep tapping splay structures within the orogenic gold bearing Otago Schist, host to the 8Moz Macraes deposit. TinOne Resources Inc. NZ has reprocessed available geophysical data sets to define the structural splays that had not previously been recognised. This regional zone of structural weakness is an ideal location for orogenic gold deposition of a style similar to the regional structurally controlled Macraes gold deposit.
