Mariners-type Mineralisation
High-grade, shallow gold target type in the Stawell Zone.
The Mariner’s-type mineralization is an important part of the exploration model at North Stawell Minerals. The Mariner’s-types occur as sediment-hosted quartz vein splays above the deeper basalt that can be “followed” to find deeper, basalt-flanking mineralisation as seen at Stawell. The Mariner’s Lode at Stawell is also notable for its excellent historic gold endowment (approx. 1Moz Au at 30 g/t Au historic production[8]) and is attractive target for exploration above identified basalts.
Interested in some extra geological detail?:
The Mariners Lodes, part of the Hanging Wall Lodes at Stawell, is a significant part of the Stawell gold mining complex in Victoria, Australia. It represents a specific type of gold mineralization within the larger Stawell gold system[1][2] – a series of sub-parallel lodes hosted by faults and shear zones above the western flank of the large basalt butress known as the Magdala Anticline[4].
The Hangingwall Lodes were an important source of early production, yielding ~30t of gold between 1856 and 1880 at ~30 g/t Au [8] (nb this is historic production – not in-ground resource). They are hosted by white mica-altered portions of the Albion Formation, located within and adjacent to the Stawell Fault and in intersecting flat faults. These lodes occur ~100 to 300 m above the Magdala Basalt (boxed area, Figure 1)
Geologically, the Mariners Area is a fault zone formed by the diverging Fault Splays which form a ‘wedge’. The faults have a high graphite content, which has enabled both faults to capture remobilized gold [7]. The Mariners Lode also differs to Stawell-types in that it is mostly brecciated quartz rather than a laminated quartz vein. The lode structures are generally identified as a quartz-sulphide rich shear zone with varying widths of 2m to 10m. Gold occurs as free native grains in quartz and in association with an arsenopyrite-pyrite-chalcopyrite-sphalerite-galena assemblage [5].The mineralized zones of the Mariners Area strike at around 335° and dip around 50° towards the southwest. All shear zone lodes differ from the typical Central Lode structure due to having diffuse boundaries on both the hangingwall and footwall of the structures.
In the broader context of the Stawell gold field, the Mariners system ultimately links to the Central Lode and Golden Gift lodes, which occur on the margin of the basalt and continue to a depth of 1.6km[1]. This interconnected system has contributed to 40 years of current mining operations, as well as the 70 years of historic production.
