The Ok Tedi mining operations are centred on the Mt Fubilan deposit located in the Star Mountains of the Western Province.
Mt Fubilan is a rich coppergold-silver deposit with several phases of mineralisation centred on two intrusions, known as the Fubilan monzonite porphyry, located in the northern half or Centre Pit area and the Sydney monzodiorite stockworks with subsequent alteration in the south. Majority of the ore is found in the sulphide skarns, located adjacent to the intrusions along the contacts with the limestone and siltstone units.
In 2022, OTML exploration concentrated on near mine targets within SML1 (New York Breccia, Wellington, Gilor 10 and Komgubip) as well as reconnaissance drilling on EL 2156 at Mt Frew and Mt Kwang.
OTML continues its resource definition drilling within the Fubilan mine area and on advanced prospects within SML1 to replace mined reserves and improve resource confidence.
Within SML1, exploration activities focused on completing the drill program on the New York Breccia, drill testing the Gilor Breccia, a program of resource drilling at Wellington, and drilling at the Komgubip prospect East of Wellington.
A total of 29 holes were completed on SML1 for an aggregate of 13,513 metres (m).
