    Pantoro hits further high-grade gold at the Norseman project

    Pantoro Limited (ASX: PNR) has announced further high-grade results from the diamond drilling program at the OK Underground Mine within its Norseman Gold Project in WA.

    The company reported new significant results of 6.05 m @ 22.90 g/t Au; 6.85 m @ 8.07 g/t Au; 1.56 m @ 59.62 g/t Au. 2.75 m @ 9.09 g/t Au; 1.35 m @ 22.89 g/t Au. 1 m @ 16.4 g/t Au; 3.35 m @ 10.3 g/t Au; and 0.3 m @ 15.0 g/t Au.

    It may be noted that these new results are in addition to the ones reported from the historic workings, which included 2.4 m @ 623.97 g/t Au; 4.6 m @ 46.40 g/t Au; and 2.17 m @ 47.38 g/t Au.

    The company said that these combined results demonstrate the lateral and vertical continuity of the high-grade O2 Lode structure and complement the limited historic diamond drilling below the lowest development levels at the OK Underground Mine.

    Norseman gold project

    The Norseman Gold Project is located in the Eastern Goldfields of Western Australia, at the southern end of the Norseman-Wiluna greenstone belt. The project lies approximately 725 km east of Perth, 200 km south of Kalgoorlie, and 200 km north of Esperance.

    Pantoro Limited had announced the major acquisition of 50% of the Norseman Gold Project in May 2019 and completion occurred on 9 July 2019. The project comprises 146 near-contiguous mining tenements, most of which are pre-1994 Mining Leases which are free of native title.

    The current Mineral Resource is 4.4 million ounces of gold. Many of the Mineral Resources defined to date remain open along strike and at depth, and many of the Mineral Resources have only been tested to shallow depths.

    Pantoro has focused Mineral Resource definition drilling on six initial mining areas containing multiple deposits that are amenable to both open pit and underground mining.

    OK Underground Mine

    The OK Underground Mine in the Norseman project is located approximately two kilometres to the south of the existing processing plant. It is made-up of three developed lodes, the Main Lode, the Star of Erin Lode, and the O2 Lode.

    The OK Underground Mine was worked on in the 1930’s but then remained idle until the 1980’s when it was reopened to focus on mining remnant ore from the Main Lode.

    The Indicated and Inferred Mineral Resource at the OK Underground Mine currently stands at 355,000 tonnes @ 18.0 g/t Au for 205,000 ounces. The mine has produced historically at an average grade of 9.1 g/t Au.

    High-grade historical results

    The company had reported high-grade results from the OK Underground drilling in April 2020.

    Significant hits included 2.4 m @ 623.97 g/t Au; 4.6 m @ 46.40 g/t Au; 2.17 m @ 47.38 g/t Au; 3.4 m @ 8.92 g/t Au; 2.18 m @ 10.05 g/t Au; 1.6 m @ 13.52 g/t Au; 5.7 m @ 11.07 g/t Au; 3.1 m @ 12.65 g/t Au;  3 m @ 6.18 g/t Au; 1.95 m @7.25/t Au; 1.5 m @ 6.28 g/t Au; 1.27 m @ 59.27 g/t Au.

    New underground drilling program at OK Underground Mine

    Pantoro had recently commenced diamond drilling at the OK Underground Mine to extend the depth of defined mineralisation in the 02 Lode below the 22 Level, and to infill the Star of Erin Lode mineralisation. The initial phase of the drilling focused on the central portion of the O2 Lode.

    It may be noted that the gold in the O2 Lode is free milling and typically hosted by a very narrow (0.3 metres average width) laminated quartz veins which are commonly surrounded by up to two metres of predominantly biotite alteration.

    The company reported that it has completed approximately 7,586 metres in this program with a number of results still outstanding.

    High-grade results from O2 Lode

    New high grade results below existing development on the 22 level include 6.05 m @ 22.90 g/t Au; 6.85 m @ 8.07 g/t Au; 1.56 m @ 59.62 g/t Au; 2.75 m @ 9.09 g/t Au; 1.35 m @ 22.89 g/t Au; 1 m @ 16.4 g/t Au; 3.35 m @ 10.3 g/t Au; and 0.3 m @ 15.0 g/t Au.

    The company announced that the combined results demonstrate the lateral and vertical continuity of the high grade O2 Lode structure and complement the limited historic diamond drilling below the lowest development levels at the OK Underground Mine.

    Updates and future work

    PNR announced that the drilling is now complete on the O2 Lode for the current evaluation with a further thirteen holes to be logged, assayed and reported.

    The company said that an infill drilling program has commenced on the Star of Erin orebody which is easily accessible from the current underground development.

    Pantoro said that the dataset of the drilling results will be utilised in an update to the current Mineral Resource for the OK Deposit. The company said that further infill drilling will be planned on the basis of interpretation of the results as they become available.

    PNR reported that a Mineral Resource modelling is underway for the Norseman project and due for completion in the September quarter.

    Management comments

    Pantoro’s Managing Director Paul Cmrlec said: “These additional results from the OK Underground Mine demonstrate the consistent high-grade nature of the deposit beneath the historic workings.

    The decline at OK has been fully rehabilitated and recommencement of production activities will be relatively straightforward.

    The outstanding results that the drill program has delivered gives us confidence that the OK Underground Mine is likely to be one of the first developments when we Pantoro restarts operations at Norseman.”
