The Deflector Extended Project licence (E59/1657) comprises a single exploration licence of 5 blocks, about 15km2, which was granted on the 12 July 2011, for a period of five years. On the 30 September 2016, the licence was renewed for a second, five year term, to the 11 July 2021, with no reduction in area. This is the only tenement held by MinRex in the Gullewa area.
The Daltons Project licence (E45/4681) comprises a single exploration licence of 3 blocks, equalling about 9km2, which was granted on the 13 July 2017, for a period of five years. The licence contains a line of old workings spaced over a length of about 2km, variously named Daltons, McLeods Reward, Thomas and Eclipse. The lease is remote and best accessed by driving 72km south on the Marble Bar-Hillside road (unsealed), crossing the Shaw River, and then driving 17km by weak tracks into the lease area – the 89km drive takes about 2 ½ hours and the last 17km of track driving is difficult. The long access time dictates that work in this area requires camping on site.
The Marble Bar North Project licence (P45/3040) comprises a single prospecting licence of 3.025 hectares, which was granted on the 2 July 2018, for a period of four years. The lease is 3km from Marble Bar Township, with a well maintained track running right to the old Ironclad mine-site and battery, a five minute drive from Marble Bar.
The Marble Bar South Project licence (P45/3039) comprises a single prospecting licence of 8.26 hectares, which was granted on the 2 July 2018, for a period of four years. The lease is 11km south of Marble Bar Township, on the main Marble Bar-Hillside Road, and has a weak old track running through the lease, a fifteen minute drive from Marble Bar.
The Heemskirk Tin Project lies in exploration licence EL18/2011, on the west coast of Tasmania (Figure 2). MinRex has now held its Heemskirk Tin Project since 2012 and has been successful in identifying a number of the old tin workings, dating from the 1870’s-1880’s, and has collected a total of 129 stream sediment concentrate samples, 99 rock chip samples and 78 soil samples, for a total of 306 samples, in a search for large low-grade, or smaller, high to medium-grade tin deposits (Figure 1).
