About Lewis Ponds
The 100% owned Lewis Ponds project covers approximately 148 km² located 15 km east of Orange (EL5583). This is a high priority project for Godolphin due to the extensive historic gold and base metal workings, with a JORC (2012) Mineral Resource estimated at 9.83 million tonnes (5.01Mt Indicated, 4.82Mt Inferred) at 1.49g/t gold, 66.15g/t silver, 2.46% zinc, 1.38% lead, 0.15% copper (ASX announcement dated 12 August 2025).
The Lewis Ponds area was an active mining centre from around 1884 till the 1920s. The workings were centred around two major areas; Main Zone (also called Spicers Mine) and Tom’s Zone. Main Zone was actually the site of a smelter and an adjacent limestone quarry – postulated to be a flux source. Spicers Mine was reported to have produced around 6000 t of ore at 6.7% lead and 187 g/t silver (Rowe, 1999). Tom’s Zone was reportedly a pyrite mine and was in operation from 1913 to 1921.
Historical workings are extensive, consisting of numerous shafts (mostly collapsed and shallow) and shallow surface workings. These locations were mapped by Ardea Resources to assist in identifying the surface expression of mineralisation and hence assist in the creation of a geological\mineralisation model.
Around two to three kilometres south of the Main Zone workings, there is another group of workings including; Mt Nicholas, Brittania, Icely and Ophir Copper Mine.
In the western part of the tenement, around Mt Bulga, there is a line of workings and mineral occurrences running over a distance of approximately 6 km. The Mt Bulga Mine was reported to have a copper grade of 6.5% and also has a historical resource from 1970.
In the far northern part of the tenement, west of Summer Hill Creek, there are numerous workings and occurrences around the historical Mt Lindsay copper mine.
Historical mining, drilling and exploration at Lewis Ponds focussed on sedimentary base metal models and not gold.
Work by Godolphin team during 2021 confirmed significant gold and multielement anomalism at Lewis Ponds similar to the nearby two-million-ounce McPhillamys Gold Deposit. The McPhillamys Gold Deposit is one of Australia’s largest, under development open pittable resources situated 20 km south east along the Godolphin Fault Zone.
During 2022 Godolphin completed a four-hole reverse circulation (RC) drill program at the Quarry Lode, testing for mineralisation near surface and to the northwest of the current MRE. All four holes intersected gold, silver and base metal mineralisation and was followed by the completion of a soil sampling program in Q4 north of the Lewis Ponds deposit.
2024 to 2025 Diamond Drill infill program and review of historical data, exceeded expectations and highlighted the exceptional potential for the Lewis Ponds project. Through infill drilling and improved geological understanding of the Spicer’s and Tom’s Lodes and the introduction of a portion of the Torphy’s Lode, the updated Mineral Resource, reported 12 August 2025, showed a significantly increased global resource metal inventory, including 58% more tonnes, an 18% uplift to the contained gold to 470,000oz, and a massive 31% increase to the contained silver metal to 21Moz.
Geology
The Lewis Ponds deposit lies on the east limb of the Mullions Range Anticline and is hosted within the Late Silurian Mumbil Group. The actual mineralisation is hosted within the Anson Formation, a fining up sequence from a conglomeritic base to siltstones at the top. The stratigraphic sequence has been metamorphosed to lower greenschist facies. Other deposits in the region with similar mineralisation styles include; Daydawn, Calula, Mt Lindsay, Icely and Mt Bulga.
Within the sulphide lenses at Lewis Ponds, alteration varies in intensity, mineralogy and distribution. Dip of the mineralised zones is generally steep to the northeast, however they can range from vertical to more steeply westerly dipping.
The most prominent regional structure is the Lewis Ponds Fault, located less than one kilometre to the west of Lewis Ponds, which is interpreted as a splay off the Godolphin Fault.
Two series of faults have been noted at Lewis Ponds, one regular set strikes southwest-northeast and dips to the northwest and a second dipping steeply and striking east-west.
The Lewis Ponds polymetallic deposit is a stratabound and disseminated sulphide system and is historically considered to be of a VHMS type. Godolphin has documented a later stage deformation and an orogenic overprint that has introduced a component of remobilisation and the introduction of silica respectively into the system, as well as flexuring of the stratigraphy.
Agnew (2002) concluded that Tom’s Zone was a sheet style VHMS deposit formed at or near the sea floor, which has later been deformed, remobilised and fluids introduced by the Lewis Ponds Fault. The Main Zone however has similarities with carbonate-hosted replacement deposits, where sulphides have infiltrated into the pore spaces of poorly sorted breccias. Textures within the sulphides indicate rapid sea water quenching.
