GTI digging deep to follow historically defined mineralised trends
GTI Resources Ltd (ASX:GTR) has received an independent WAMEX compilation report, from CSA Global (CSA), assessing the historical gold production and exploration activity and potential prospectivity at the company’s newly granted prospecting licences, P40/1515, P40/1516, P40/1517 and P40/1506 and the recently acquired P40/1513 and P40/1518.
This contiguous land package over approximately five kilometres of mineralised trend now creates a significantly enlarged consolidated holding over extensive historic mine workings of the Niagara gold mining district.
The Niagara Project is located 6 kilometres south-west of Kookynie in the central goldfields of WA.
The project is within the central part of the Norseman-Wiluna Greenstone belt, and the geology of the area is characterised by large rafts of semi-continuous greenstone stratigraphy.
Numerous historical workings occur within and to the north of the project area, with a number of major historical mines located in the immediate vicinity of Kookynie, including the Cosmopolitan Propriety Ltd, which mined a total of around 630,000 tons of ore at an average grade of 15 g/t gold between 1897 and 1911 (Shire of Menzies, 2020), producing in excess of 300,000 ounces of gold.
The tenements incorporate the historic White Cross and Perseverance mining areas and smaller historic working trends including the Christmas and Good Friday trends.
The Orion Trend extends east-north-east to the south of the tenements and hosts the historic Orion/Sapphire Mine.
The compilation report from CSA highlights the material past production and drilling which has occurred on the newly consolidated land package.
Commenting on these developments, Bruce Lane said, “The report from CSA has now pulled together all of the known historical information available for the newly consolidated land package and what the report reveals has exceeded our expectations in terms of the exciting gold potential of the ground.
"We are now evaluating our options to create shareholder value from the project as we prepare a plan and permits to properly test this historically heavily worked area using modern exploration techniques.”
Historic workings in the tenement package targeted high-grade quartz veins and were largely operated between 1898 and 1914 with reported production of 6800 tonnes at 25.8 g/t gold for 5100 ounces gold.
While most intersections were fairly narrow, some high grades were returned from shallow depths such as 2 metres at 70.5 g/t gold from 7 metres and 2 metres at 15.4 g/t gold from 10 metres.
Rock chip samples also featured high grades including 165 g/t gold from the White Cliffs area and 91.8 g/t gold from the Green Bullet area.
Management targeting mineralisation at depth and along strike
Extensive historic workings and reported high-grade production in the east of the project area represent an advanced exploration play.
More specifically, the project contains three high priority advanced exploration target areas, two secondary priority intermediate exploration target areas and three earlier stage third priority exploration target areas.
As historical drilling typically extended to a maximum depth of 50 metres, management intends to target deeper levels where known mineralisation exists, and along strike from established trends.
The mineralised trends that represent high‐priority, advanced exploration targets in the east of the project area are collectively up to 2.5 kilometres in length, including 1.6 kilometres of the White Cross trend from the May workings in the east to the Jarrahdale‐Spinaway workings in the west, 400 metres of the Good Friday trend, and 500 metres of the Christmas trend.
The central and western project areas represent earlier‐stage exploration targets with records of only limited but high‐grade historic production.
