Compilation by Heathgate into a computerised in-house database of all available historic geological, geophysical and geochemical data which has originated from the project area Sampling of 5 historic sonic drillhole stored cores for laboratory assaying (437 samples). The results when compared to gamma ray log - derived mineralisation grades have indicated that positive uranium disequilibrium exists in places at Goulds Dam, with 2 sonic hole cores providing evidence that it may be as high as 170% Infill rotary mud appraisal drilling at Jason's prospect during November-December 2016: 54 vertical open holes for 6877 m on a nominal 200 m x 150 m hole spacing, to delineate roll front uranium mineralisation occurrences in the Yaramba Palaeochannel which were known to persist for a distance of 6 km to 21 km downstream of the Honeymoon orebody. Drilling performed in the southern portion of the prospect defined a high-grade core to the mineralisation: significant wide intercepts were made including 4 m @ 464 ppm eU3O8 from 100.65 m depth in hole BMR038, 2.5 m @ 1394 ppm eU3O8 from 105.45 m depth in BMR043, and 6.75 m @ 524 ppm eU3O8 from 103.9 m in BMR050. These intercepts lie along trend to historical drillhole YAM040 which was reported to contain 2.3 m @ 3981 ppm pU3O8 (a PFN logging tool - derived grade). Good lateral continuity of the mineralisation was also encountered by Heathgate in its latest drilling Calculating an updated mineral resource estimate for the Goulds Dam uranium deposit: now the Indicated Resource stands at 4.4 Mt @ 650 ppm eU3O8, for an orebody envelope extent of 1.5 km x 540 m, using a >100 ppm eU3O8 cut-off grade; while the Inferred Resource stands at 17.7 Mt @ 480 ppm eU3O8, for an orebody envelope extent of 15 km x 2.5 km, also using a >100 ppm eU3O8 cut-off grade Calculating a maiden Inferred mineral resource estimate for the Jason's uranium deposit, of 2.8 Mt @ 840 ppm eU3O8, using a >250 ppm eU3O8 cut-off grade During the second reporting period exploration activities completed by Boss included: • Ongoing compilation and validation of previous exploration and drilling data into a SQL database suitable for use in planning future exploration activities and resource calculations. • Native Title negotiations and heritage surveys. • Resource calculation for the Jasons prospect; and • Completion of a mud rotary and sonic core drill program on the Jasons Prospect, north of the Honeymoon mine site. Historic data compilation is aiming to provide a complete dataset of historical exploration to allow an assessment of the prospectivity of the tenements. The drilling undertaken at the Jasons Prospect was to test historical drilling with encouraging uranium intercepts and increase the uranium resources for the Honeymoon area. A total of 18 rotary mud holes for 2044 m were completed on EL 5621 at the Jason Prospect, along with 4 water bores for 456.4 m and 2 sonic core holes for 232 m. Holes were wireline logged, and gamma and PFN (prompt fission neutron) recorded. A total of 32 samples were collected from the sonic cored holes and submitted for multielement chemical analysis. Drilling in the southern portion of the Jasons Prospect has defined a high-tenor core to the mineralisation with significant wide intercepts including 4 m @ 464 ppm eU3O8 (from 100.65 m in BMR038), 2.5 m @ 1394 ppm eU3O8 (from 105.45 m in BMR043) and 6.75 m @ 524 ppm eU3O8 (from 103.9 m in BMR050).
