Extension drilling has found a new high grade zone, while infill drilling also continues to yield excellent results
() has released what it described as outstanding new results from drilling at the Havieron deposit in the Paterson region of Western Australia.
Extension drilling in the north-west portion of the property has confirmed and unearthed a new zone of higher-grade breccia mineralisation, the group said.
Newcrest Mining, Greatland’s partner and project operator, revealed the latest finding and also stated that separate infill drilling had also yielded excellent results, confirming mineral continuity within the project area.
Drill results to date support the investigation of both high-grade selective and bulk mining methods, according to Newcrest.
“The identification of a new zone of breccia mineralisation in the north-west is an important and exciting development which further highlights the potential scale and significance of the Havieron gold-copper deposit,” Greatland chief executive Gervaise Heddle said in a statement.
“The early results from step-out drilling indicate significant potential for additional breccia and high-grade, crescent-style mineralisation in the north-west of the system, similar to that observed in the south-east where the bulk of drilling has occurred to date.”
Heddle added: “Meanwhile, further excellent results from infill drilling, including 45.7m @ 6.5g/t Au, 0.70% Cu from 934.8m (HAD054W4), continue to improve grade distribution within the crescent zone and support the delivery of a maiden resource by the end of 2020. Concurrently, studies are in progress with a view to fast-tracking the commencement of a decline and accelerating the time frame for commercial production.”
Greatland highlighted the best results from drilling in its statement, the notable ones included a 182 metre intersection which had of 2.1 grams per tonne gold, and included 45 metres at 6.5 grams per tonne.
