Following the completion of the Phase 1 drilling campaign (refer TSXV: AMO March 10, 2021), the Company conducted a geological review of all technical information obtained from the drill program. The review noted significant gold mineralisation was associated with sulphide assemblages which were pyrrhotite dominant and generally ~ 2% disseminated. However, in drillhole PARC005, significant sulphides of up to 30% were logged in an interval from 201 to 206 metres associated with high grade gold mineralisation of 5 metres grading 13.93 g/t from 201 metres within a broader mineralised intercept of 8 metres grading 9.65 g/t from 199 metres. Lower tenor gold mineralisation was observed with pyrite and pyrite-pyrrhotite sulphide assemblages. The Company commissioned Newexco Exploration Pty Ltd ("Newexco"), a Perth-based geophysical and geological consultancy group, to investigate the application of DHEM in order to target gold mineralisation in sulphide-rich zones. Initially, drillhole PARC005 was surveyed due to the high sulphide content observed during logging and the three gold mineralised intercepts reported. Attachment 1 provides a pictorial summary of the three mineralised intercepts, the individual metre gold grades and the logged percentage of sulphides. Drillhole PARC014 was surveyed as a follow-up to provide further information relating to the information obtained in drillhole PARC005. Commenting on the results, Altan Rio CEO Mr Paul Stephen said: "This is a significant development at the Pilot deposit where Altan has now demonstrated the potential for the application of geophysical techniques to directly apply to gold exploration in the immediate area around Pilot and potentially elsewhere in the Southern Cross North Project. Identification of the PEM 4 conductor is particularly exciting with modelling suggesting the strike extent of the high-grade gold mineralisation is substantially greater than what was observed on the 4 Level of the historical underground workings. The company is eager to follow-up on our consultants' recommendations with planning for additional EM surveys and future drilling in progress."
