Challenger Exploration Limited announce results from drilling at its Hualilan Gold Project, San Juan Argentina. The results are from the Company's ongoing drill program targeting extensions to the current 2.1 million ounce AuEq Mineral Resource Estimate. These results will feed Into a planned mineral resource update in the first quarter of 2023.

The results, from extension drilling at Sentazon which is the southern limit of the current MRE, demonstrate a significant increase in the scale of the mineralisation at Sentazon. The strike extent of Sentazon has been extended from 150 to 250 metres with mineralisation remaining open along strike to the south. Additionally, drilling has confirmed the discovery of a significant new zone of high-grade mineralisation at depth "Sentazon Deeps: which has been intersected in several drill holes.

Sentazon continues to grow in importance. It was historically lightly drilled as it was considered to be complex and of limited in extent. Sentazon contributed 333,655 ounces of gold equivalent at a grade of 5.3 g/t AuEq2 to the current 2.1 Moz Mineral Resource Estimate and mineralisation at Sentazon remains open along strike and at depth and continues to expand.

The first indication of a new zone of mineralisation at depth at Sentazon was a 350 metre extension to drillhole GNDD-302 which intersected 15.6 metres at 1.0 g/t AuEq from 467.0m including 1.7 metres at 6.4 g/t AuEq and a second zone of 4.3 metres at 4.0 g/t AuEq from 510.8m including 1.1 metres at 14.4 g/t AuEq.
