Corkscrew GR198-11 Annual Group Report 27 February 2017 to 26 February 2018 EL 10120 and EL 23509 Hayes Creek Project

Abstract

Since purchasing the Hayes Ck project from Thundelarra early in 2014, Rockland Resources has undertaken significant due diligence work, deposit studies and field activities including drilling and airborne electromagnetics. There has been assessment and compilation of the previous geological, geochemical and geophysical exploration data along with integrated targeting analysis. During the reporting period a trial SkyTEM airborne electromagnetic survey has been completed over selected areas of the project. The survey has been completed over a) the Priscilla prospect within EL 10120 totalling 2.75 line km, b) the south west corner of EL 23509 (just west of the Davies prospect and MCN 4267) for a total of 7.6 line km, and c) west of Thunderball within EL 23509 for a total of 2 line km. This survey has confirmed a 2011 VTEM anomaly at Priscilla and identified a new anomaly nearby. In addition, there are VTEM anomalies .5-1 km south of Priscilla. These anomalies should be followed up with ground electromagnetics to identify precise drill targets for VMS mineralisation and likelihood the anomalies are geological rather than due to culture. Rockland's assessment of the historical drilling has re-affirmed the Priscilla prospect as a high priority target where drill to date has encountered up to 4 m (36-40 m) at 229.3 g/t and 4 m (16-20 m) at .9 g/t Au in hole TPCRC159. Integrated targeting has highlighted the possibility of a new mineralised corridor which stretches north north-west, linking to mineralisation in hole TPCRC167 (4 m at 11.8 g/t Au) located 230 m away, and also mineralisation a further 200 m away in hole TPCRC161 (4 m at 2 g/t Au). This prospective corridor covers a relatively large area with potential to host economic mineralisation. Integrated targeting has successfully identified several mid-high priority targets predominantly within EL 10120. There are positions northeast of Moonraker and west of Priscilla which have not been drill tested but have similar geology to other deposits in the area (i.e. Lower Mt Bonnie Formation west of the main anticline trend); New sub-surface parasitic anticlines have been identified from the magnetic and electromagnetic data along the western part of the tenement (upper Mt Bonnie Formation); The last 4 m composite in hole TPCRC176 has high uranium pathfinder elements (i.e Pb/Cu of 21.17) but was not assayed for uranium or other key elements; Soil geochemistry anomalies have been identified which appear to have not been targeted by drilling: A soil sample (LLFA soil sample D41238) has extremely high gold of 1.015 g/t Au, located 102 m northwest of hole TPCRC175; A soil sample (LLFA soil sample D51755) has elevated gold of .85 g/t Au, located 243 m west of hole TPCRC159 and 127 m southwest of hole 93YCRC008; Two auger vacuum drilling soil samples located 50 m apart have extremely high gold of 2.379 and 1.085 g/t Au (LLFA soil sample B18498 and B18499) on the edge of Crocodile Gold mining licence MCN624 but could be followed up within Rockland's ground immediately south within EL 10120; Several LLFA soil samples from two lines (i.e. sample D41227) have high As (to 330 ppm) and weak Au (.09 g/t which is twice background) along a trend 200-400 m southwest of hole TPCRC175; and MMI samples by Northern Gold are up to 40 times background (ie. sample 150093 to .046 g/t) located 230 m north of TPCRC175. Each of these areas requires detailed prospecting and multi-element soil/chip sampling. An orientation geochemical program (soil and drill-hole geochemistry/pXRF) should be conducted at the Osborne South and Priscilla prospects to refine the methodology and signature. The Priscilla Line is covered by recent sediments and also historical alluvial mining/prospecting, which may adversely affect the ability of geochemistry to correctly identify basement mineralisation. To assist with targeting ahead of drilling, Sub-audio magnetics (SAM) and VTEM is proposed. The VTEM has proven ability to map carbonaceous lithologies in 3D. SAM has not previously been utilised in the region and may provide an important new tool to map in detail resistivity changes related to controlling shears and quartz-bearing structures. Project scale gravity is being considered to interpret sub-surface intrusions and aureoles to guide regional target filtering and prospectivity for gold mineralisation.
