Tomingley Deposits: Wyoming One, Caloma, Caloma Two.Mineralisation is associated with quartz veining and alteration focused within sub-volcanic basalticandesite sills and adjacent volcaniclastic sediments. Thedeposits appearto have formed asthe result of a rheological contrast between the porphyritic sub-volcanic sills and the surrounding volcaniclastic sediments, with the sills showing brittle fracture and the sediments ductile deformation, and have many similarities to well documented orogenic - lode-style gold deposits.Wyoming OneMineralisation at Wyoming One is developed within a number of different zones which have been domained based on the geology, style of mineralisation and continuity of high mineralisation that can be separated:* Porphyry – mineralisation hosted by a quartz stockwork within the carapace of a sub-volcanic sill with dimensions roughly 60m x 150m. High grade mineralisation is developed along the eastern and northern contact of the sediment and porphyry. This High Grade mineralisation on the contact has been domained separately for the estimation and is currently referred known as the “High Grade 101 porphyry lode” mentioned below. Within the main porphyry body there are several internal mineralised stacked lodes that dip 45° to the NE. These structures were evident from the close spaced open pit RC Grade control drilling. Underground Diamond drilling has confirmed these stacked lodes and the targeting and defining of more internal porphyry mineralised structures will be a focus as mining continues.* Hangingwall – a linear zone of mineralisation situated approximately 30m to hanging wall of the ‘porphyry’ mineralisation and hosted within quartz veins within silicified fine grained sediments and a brecciated carbonaceous mudstone. This zone is lithologically constrained with these fine grained sediment package which folds around the northern end of the porphyry;* High Grade 101 Porphyry Lode”’ –This zone was previously known as the ‘376” structure interpreted to be a bounding structure and primary fluid conduit. This High Grade zone of mineralisation is developed at the eastern and northern contact of the porphyry and incorporates some of the contact metasediments which were impacted by the mineralisation.* Footwall – a low grade zone located in a similar stratigraphic position to the hangingwall zone but footwall to the porphyry.CalomaMineralisation at Caloma is developed within a series of stacked ‘quartz lodes’ which dip shallowly to the west and hosted dominantly within the sub-volcanic sills. The lodes are cross cut by a number of barren post mineralisation dolerite dykes.Caloma TwoMineralisation at Caloma Two is developed within a series of ‘quartz lodes’ which dip north at flat to moderate angles and hosted dominantly within the sub-volcanic sills. Mineralisation is also developed along a sediment contact zone which appears to be a potential linking structure with the Caloma mineralisation to the north. There is also evidence for the development of an inverted saddle reef at depth. The lodes are cross cut by a number of post mineralisation dolerite dykes.
