Investigator Resources' (ASX:IVR) success in discovering the 20 million ounce Paris silver deposit in South Australia is relatively well known.
Perhaps less well known is the Paris deposit may be just a forerunner of finding additional deposits in the emerging Uno Epithermal Province.
Improved targeting after a challenging 2014 provides better potential for flow on discoveries for Investigator after Paris.
The Paris silver deposit has a similar geological setting to the world-class Imiter silver mine in Morocco, with a massive resource of 290 million ounces of silver and underground production of 7.7 million ounces a year grading circa 440g/t silver.
Covered extensions to the ironstone are the frontrunner for testing a new target style of high-grade silver deposits.
Recent work indicates that there could be 20 kilometres of prospective extensions to the Paris geological setting along the southern side of the Uno Fault.
Investigator has first mover advantage in the Uno province, never a bad thing.
There are a number of first-pass soil targets for silver, copper and gold of similar size and geological position to those of the Paris silver deposit nearby.
Hence the work and promise afforded by the new Thurlga tenement, located at the western end of the Uno Epithermal Province and adjoins the western margin of the Peterlumbo tenement 8 kilometres from the Paris silver project.
Thurlga is a joint venture with Adelaide Resources (ASX:ADN) and has identified six early silver, gold and copper targets in initial exploration of the Thurlga tenement.
A significant advance has been made in the understanding of the target model for the Paris district.
Associated potential for higher-grade silver deposits is recognised in the Uno Fault and parallel fault splays around Paris including in the Thurlga JV area.
A strong northeast structure named the Thurlga Fault is similar to northeast structures at Paris, Menninnie Dam and Parkinsons Dam along the 140 kilometre length of the Uno Fault.
Now the structures are considered to localise silver-dominant epithermal mineralisation in offsets to the Uno Fault so this prospect offers an unexplored opportunity for new discoveries to be made near Paris.
In March 2015, regional soil sampling was completed on a 500m by 500m grid over the target areas as determined by the magnetic surveys.
A total of 747 samples were collected and were submitted to an accredited laboratory for the “standard” 32-elements analysis.
There is potential for obscured high-grade silver deposits in the Paris-Thurlga district that will have subtle target signatures and can potentially bear deeper mining
Within the Thurlga project infill soil sampling and prospecting are underway for the Starburst North, Jaffa, Longhop, Yorker and Ironstone areas.
This should generate more finely honed drill targets.
The Thurlga tenement EL5419 is subject to a JV farm-in agreement with Adelaide Resources, that gives Investigator the right to earn 75% interest in the Thurlga tenement.
