Southern Hemisphere Mining Limited reports that results from the latest RC drilling program at its Llahuin Copper-Gold-Moly Project are starting to be received from the LAS Laboratory in Chile, with results from 7 holes reported in this release.

The drillhole locations are shown in Figure 1.

  • The RC drilling program at Llahuin which began in December 2021 has been completed with 24 holes drilled for 2,787m
  • First results have been received from the ALS Laboratory in Chile for 11 holes, with a best result at the Central Porphyry, so far of 90m @ 0.62% CuEq from surface which is significantly higher than the published resource grade (0.41% CuEq)
  • Drillhole 21LHRC009 at the Cerro De Oro deposit intersected 69m @ 0.47% CuEq from surface
  • First RC drillhole into the Southern Porphyry Copper/Gold Target intersected approx. 177m with trace visual chalcopyrite.

The drilling program was designed to test:

  1. Near surface higher grade zones in and around existing resources at the Central Porphyry and Cerro De Oro deposits, and
  2. New targets for large porphyry deposits.


Drillholes at the Central porphyry and Cerro De Oro were infill drilling off existing drill pads targeting near surface material. Drillhole 21LHRC009 intersected a newly recognised near surface zone 0-69m @0.47%CuEq which will require follow up drilling to better define the extents and its relationship to the Cerro deposit.


  1. Southern Porphyry Copper/Gold Prospect
  • Drillhole 22LHRC024 was the maiden drillhole into the Southern Porphyry Copper-Gold prospect, is considered by the company to be a technical success intersecting 177m of trace visible chalcopyrite in the first hole of the program, with assays pending.
  • The hole was designed to test historical rockchip data and newly acquired drone magnetic survey data. Further drilling is planned to test the Southern Porphyry target.
  1. The Railway prospect
  • Two drillholes were completed at the Railway copper/gold prospect, and both intersected continuous sections of Copper/Gold mineralisation, from surface to end of hole in holes 21LHRC010 and 11.

The next stage of drilling 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.

Approximately 40% of assays have been received from the ALS laboratory in Chile and significant results are presented in Table 1 below.

NB: Copper Equivalent CuEq% calculated using Cu $3.20lb, Au $1700/oz Ag $20/oz and Mo $30/kg.

Further assays are pending and the results will be reported in due course when they become available from the laboratory and analysis is complete.

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.

In relation to the disclosure of visual mineralisation, the Company cautions that visual estimates of sulphide abundance should never be considered a proxy or substitute for laboratory analysis. Laboratory assay results are required to determine the widths and grade of mineralisation. The Company will update the market when laboratory analytical results become available.

The information in this report that relates to copper and gold exploration results for the Company’s Projects is based on information compiled by Mr Adam Anderson, who is a Member of The Australasian Institute of Mining and Metallurgy and The Australian Institute of Geoscientists. Mr Anderson has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration, and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves”. Mr Anderson is a consultant for the Company and consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.


Southern Hemisphere Mining Limited is an experienced minerals explorer in Chile, South America. Chile is the world’s leading copper producing country and one of the most prospective regions of the world for major new copper discoveries. The Company’s projects include the Llahuin Porphyry Copper-Gold-Moly Project, the adjacent Colina 2 Gold Project, and the Los Pumas Manganese EV Battery Project, all of which were discovered by the Company.
