The company this week reported latest results from 6,430m of resource infill, step-out and exploration drilling on Cangrejos and Gran Bestia, with highlights including two step-out intercepts from Cangrejos of 302m grading 1.22 grams per tonne gold and 0.14% copper from surface, and 175m of 0.65g/t gold and 0.08% copper from 28m depth.

Infill drilling at Cangrejos also returned 26m of 2.06g/t gold and 0.77% copper.

Lumina said it intended to test the northern ridgeline area at Gran Bestia before completing an updated resource estimate on Cangrejos by November. The ridgeline remained open to the northwest, where step-out holes were targeting the longest intercepts recorded to date.

At Gran Bestia infill drilling returned 184m grading 0.46g/t gold and 0.11% copper, and 220m grading 0.42g/t gold and 0.07% copper.

Further infill drilling at Gran Bestia cut long intervals of moderate-grade mineralisation from surface.

Lumina believes it may have reached the southern and eastern margins of the Gran Bestia deposit, but drilling on the Corridor zone has extended mineralisation well beyond previously assumed limits of the main resource. The company said it continued to work on modelling of Corridor zone mineralising controls.

Lumina's Toronto-quoted equity (TSXV:LUM) is trading 20% higher in the year to date at C65c, which gives the company a market capitalisation of $201.2 million.
