Pintanos

Highfield released a maiden MRE for the Pintanos Project to the ASX on 20 November 2013. During the year ended 30 June 2017, two drill holes were completed at the Pintanos Project (see the Company’s ASX Quarterly Activities Report released on 24 April 2017). The results of both holes were unfavourable compared with the block model which informed the maiden MRE released on 20 November 2013 and therefore adversely impacted the tonnage available to be classified as inferred resources. As a result, a revised MRE was prepared and reported in the ASX Additional Information section of the Company’s annual report for the year ended 30 June 2017, as summarised in Table 4 below. The Company continues to believe the exploration potential for Pintanos remains strong and will continue exploration of the project.

The Company considers this MRE remains accurate as at 31 December 2021.
