No work was completed on the subject three tenements during the 2010 reporting period, because the JV's focus then was to explore areas closer to the Beltana mine. However, it was believed that several other high priority base metal - prospective target areas exist on these tenements, and it was intended that they would become the subject of upcoming surface geochemical sampling, to be performed via hand-held Niton XRF instrumental scans plus selected rock chip sample assaying. Diamond drilling might be undertaken subsequently, depending on the geochemical results obtained. During the 2011 reporting period, no field work was performed on any of the project licences. However, late in 2011 a set of regional coverage Aster satellite multi-spectral data was purchased for the entire project area, including the entirety of the Minotaur JV tenements. These remotely sensed mineral signatures data were acquired for two main purposes, firstly, to identify outcrop areas of potentially unrecognised carbonate strata which may be prospective for zinc silicate mineralisation, and secondly, to identify areas of iron enrichment that are suggestive of increased haematite alteration possibly related to mineralisation. Although numerous potential haematite anomalies had been identified from previous Landsat satellite photos, it was expected that the more quantitative multi-spectral data should provide a more refined method of identifying areas of more intense haematite alteration. Review and interpretation of the dataset was begun. During the 2012 reporting period, no field work was performed on any of the project licences. During 2013, the joint venture partners undertook surface soil geochemical sampling via portable XRF hand-held instrument spectrometric scans plus rock chip sampling for laboratory assaying, conducted along traverses spaced 400 m apart which crossed over various historic base metal occurrences known to exist on the project licences including the Third Plain deposit, the Blackwater Springs - Fountain Head and the Mount Rugged copper workings areas. Minor attention was also given to the Wirrealpa lead prospect. At Third Plain, additional potential was found to exist at the northern end of the 2 km long sampled area, where exposed surface willemite has been essentially untested by drilling. Significant soil anomalism was also identified at the Fountain Head sulphide prospect and north of the Blackwater Springs area. A total of 123 rock chip samples and 2208 FPXRF scans were collected. During 2014, limited FPXRF soil scans and rock chip sampling were performed at the Fountain Head, Third Plain and Linda prospects. The scans at Fountain Head and Third Plain included making infill on 100 m spacing to those scanning sites originally occupied in 2013, while work at the Linda prospect was the first done there since earlier reconnaissance mapping and rock chip sampling undertaken by Perilya in 2001. A total of 15 rock chip samples and 197 FPXRF scans were collected. No significant results were returned by the FPXRF scanning, although it did more clearly delineate the northern termination of the Third Plain soil anomaly. During 2015, Perilya performed a significant amount of reconnaissance FPXRF soil scans and rock chip sampling on ELs 4478 and 5542 to profile extensive contact lengths of Proterozoic against Cambrian strata, besides covering several historic prospects in more detail. A total of 98 rock chip samples and 5159 FPXRF scans were collected. New base metal targets were defined at Mount Lyell and Narrina. During 2016, field work included performing regional reconnaissance surface geochemical sampling over several targets, concentrating on the Waraweena - Sliding Rock and Beltana Diapir targets. A total of 1703 soil FPXRF scan readings were taken and 25 rock chip samples collected. A campaign of exploratory RC drilling was also undertaken in September-October at the Third Plain prospect on EL 5723 and ML 4386, with 9 inclined holes for a total penetration of 919 m completed to the north of the resource area. Low to moderate grade but thin zinc silicate mineralisation was encountered to the immediate north of the existing resource envelope, but the majority of holes located further to the north along the extended Third Plain horizon did not return any significant intercepts. Hole TPRC036 intersected 11.0 m @ 3.13% Zn, including 1.0 m @ 23.3% Zn, and hole TPRC037 intersected 5.0 m @ 3.26% Zn, including 1.0 m @ 9.27% Zn. A gravity anomaly that was tested by hole TPRC041 was interpreted as being caused by strong karst development within the carbonate strata encountered. During 2017, work included regional reconnaissance and infill XRF soil surveying (1722 readings) and rock chip sampling (15 samples) over select target areas within the project area. Reconnaissance work at the Waraweena target area identified a strong zinc anomaly associated with Callana breccias. Significant base metal anomalism was also identified at the Eregunda Creek and Fountain Head prospects. Infill and extensional surveying in other areas including the Erina Waters, Blackwater Springs, Wirealpa Springs, Wirealpa Pb and Third Plain South prospects failed to define any additional anomalism. Strong but localized Cu-Pb-Zn results were also returned from and area of historic workings at the Mt Rugged target area (Cu up to 5.5% and up to 6372 ppm Zn and 3278 ppm Pb). Additional work included rock chip sampling at the Ti-Tree Gorge prospect as well as ongoing, progressive rehabilitation of 2016 RC drill sites at the Third Plain deposit area. At Wararweena/Sliding Rock, strong anomalous soil readings from one area returned values up to 2199 ppm Zn, with the anomaly having a strike length of 300 m in an area underlain by Cambrian aged rocks associated with the Callana breccia. XRF soil surveying targeting the area west of Blackwater Springs identified strong base metal anomalism of up to 6,113 ppm Zn and 1,735 ppm Pb. During the 2018 reporting period significant work was undertaken in the North Flinders Project area. Reconnaissance pXRF soil surveying and rock chip sampling was completed in order to better define potential drilling targets for the following reporting period. total of 6,243 in-situ soil readings were collected and 34 rock chip samples collected and submitted for major and trace element analysis. Significant targets were identified or better refined, while others were able to be down graded with no further work recommended for them. Strong anomalism was defined at the Black Range Springs prospect at the eastern end of the Waraweena target. The anomaly has a strike length of ~700m with an intensity of up to 5,179 ppm Zn and 4,561 ppm Pb in soil and occurs at the prospective contact between Wilkawillina limestone and Callana breccia. Work within the Mt Rugged target area defined a strong Zn-Pb-Cu anomaly with a strike length of ~500 m entirely within the Callana breccia, with pXRF soil readings retuned up to 6,350 ppm Zn, 4,313 ppm Pb, and 2,114 ppm Cu.
