Kalamazoo Resources (ASX: KZR) has completed the first large-scaled gold focused exploration program at The Sisters project in Western Australia’s Pilbara, with the company noting the project hosts similar mineralisation to De Grey Mining’s (ASX: DEG) nearby Hemi gold discovery.
Exploration activities at The Sisters have involved an extensive surface geochemical program in addition to aeromagnetic and radiometric surveys – targeting the Wohler Shear Zone which extends 14km over the project.
According to Kalamazoo, the Wohler Shear Zone is a prospective splay from the Tabba Tabba, Mallina, Withnell and Bergaus shear zone complex that hosts much of De Grey’s Pilbara resource including Hemi, which is part of De Grey’s Mallina project.
Since discovering Hemi last year, De Grey has defined mineralisation along 850m in strike 1,000 in width and to 300m depths.
Results at Hemi’s Aquila zone have included 51m at 2.1g/t gold from 108m, 62m at 1.4g/t gold from 59m, and 20m at 2g/t gold from 142m.
While drilling at the Brolga zone has returned 43m at 1.9g/t gold, 36m at 3.2g/t gold and 43m at 1.9g/t gold.
“The Sisters gold project has always been rated very highly by us and this has been further reinforced by De Grey’s spectacular world class gold discovery along strike at Hemi,” Kalamazoo chairman and chief executive officer Luke Reinehr said.
“We have been systematically increasing our knowledge of the area and utilising innovative technologies to assist us in identifying potential drill targets and these completed soil sampling and aerial surveys will play an important part in our search for a gold discovery at The Sisters,” he added.
Advancing The Sisters gold project
Kalamazoo’s The Sisters gold project encompasses 136 square kms and is believed prospective for epigenetic gold mineralisation associated with the Wohler Shear Zone as well as intrusions similar to Hemi, which is 50km to the north-east.
The company’s previous work has identified a 3km long soil anomaly that has returned up to 80 parts per billion gold, plus two gold nuggets to the south-west of the anomaly.
As part of the recently completed exploration initiative, Kalamazoo contracted MagSpec Airborne Surveys to fly the UltraFine+ surveys over the project.
The survey was undertaken to adjoin Sayona Mining’s (ASX: SYA) work in 2017.
Kalamazoo will then merge data from Sayona’s survey and its recently completed one at The Sisters.
The company pointed out that De Grey had used the Ultrafine+ survey at Mallina to refine its drill targets.
