  • Remaining results for the RC drilling program at Llahuin which began in December 2021 have been completed with 24 holes drilled for 2,787m in total.
  • The Central Porphyry returned a best result in hole 22LHRC022 of 104m at 0.51% CuEq from 6m to end of hole.
  • Best result at Cerro de Oro was in 22LHRC013 which intersected 51m at 0.48% CuEq from 7m depth to end of hole.
  • New target at the Southern Porphyry intersected a zone of 11m at 0.25% CuEq from 58m depth to be followed up also testing a previously untested IP target.

Note holes were designed to test near surface higher grade and thus several holes end in mineralisation.

The drillhole locations are shown in Figure 2.

Drilling at Llahuin during the completed RC Drilling Program.


The next stage of drilling is starting this week and will comprise a small orientated diamond drilling program designed to verify structures and densities at both the Central Porphyry and Cerro De Oro deposits.

Data from this program will guide further near surface drilling this year.

All of the assays have been received from the ALS laboratory in Chile and significant results are presented in Table 1 below.

Note: there has been insufficient exploration to estimate a Mineral Resource at the Southern Porphyry target and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Turnaround times for the laboratory have increased due to personnel issues associated with COVID.
