Navarre’s Stawell Corridor Gold Project comprises two exploration licences, Tatyoon and Ararat, which includes the historic Ararat Goldfield. It is located between 10 and 70 kilometres south-east of the Stawell Gold Mine which is owned by Navarre’s largest shareholder Kirkland Lake Gold Ltd.
Approximately 6 million ounces of historic and modern gold production has occurred from Ararat and Stawell.
The Irvine prospect is located 15 kilometres south of Stawell’s Magdala Gold Mine and was identified in 2015 (NML ASX release 12 June 2015). The prospect occupies the northern end of the Ararat Goldfield, which is estimated to have produced approximately one million ounces of gold mainly from alluvial and deep lead production during the period 1854 to 1925.
Production of primary hard-rock gold from the Ararat Goldfield was low given the richness of the alluvial deposits, in contrast to the Stawell Goldfield, and is one of the reasons why Navarre is searching for economic primary gold mineralisation in the vicinity of the richest alluvial gold deposits.
The largest gold mine along the Stawell Corridor is the Magdala Gold Mine, which has produced gold from a deposit that has been mined to depths in excess of 1,600 metres below surface. Modern gold mining at Stawell has been continuous from 1982 until December 2016 with the Magdala gold deposit contributing more than 4 million ounces of the total 5 million ounces of gold produced to date from the Stawell Goldfield.
Gold mineralisation of the Stawell style occurs proximal to the margins of large basalt dome structures. The basalt structures are rigid and do not deform as much as the surrounding sediments. The deformation leads to the creation of voids allowing quartz veining and gold mineralisation to form around the basalt margins.
The Company completed an AC drill program in mid-December 2016 testing the potential for the Irvine gold prospect to be an analogue of the multi-million ounce Magdala gold deposit located on the opposite side of the Stawell Granite in similar rocks to the north. The program was targeting the primary reef source to approximately 1 million ounces of alluvial gold production mined during the 19th century on the Ararat Goldfield. This drilling resulted in the discovery of the Resolution Lode etc.
