Lake Cargelligo offers major exploration opportunities in the Cobar Mining District of New South Wales.
~62,300ha of gold claims, 100% owned by Lancaster.
Multiple depositional environments for gold mineralization. Both intrusive-related gold systems (IRGS) and lode-type on the property.
Historical geochemistry shows high-grade samples up to 204g/tonne-Au and 273g/tonne-Ag.*
PROPERTY:
UPSIDE ATTRIBUTES:
Large Land position in sought after active mining area
Proximal to existing gold mines
Expected 30-50koz-Au/yr at Mineral Hill
Easy, all-season access to property
Multiple targets on claims with significant strike length
Large scale IRGS mineralization as sheeted vein & breccias
Shallow oxide, lode-style, Au-Ag mineralization
Shallow/surface colluvial deposits with free gold
Up to 204g/T-Au and 273g/T-Ag in historical sampling program1
Past Drilling has shown gold mineralization in multiple zones, but only small area tested
Ownership on ~62,168ha
Past operators identified large scale geochemical anomalies on claim block that were not drill tested for IRGS
No modern magnetics, IP, or VTEM work completed over project area
State Highway and Railway run through the property
Similar Geology to Tintina Gold Area in Alaska
Significant land base allows for multiple mineralization opportunities and is very under explored
Large scale, structural faulting along granite sedimentary contact (~25km strike length) with widespread Au-Te-Bi-As-Mo-Sb anomalies
Sedimentary lithology intruded by Silurian granodiorite and S-type Ungarie Granite
Exploration focus on ~18km contact zone between Ungarie granite and sedimentary rocks in southern half of mineral claim (Eastern Contact Zone)
8 identified targets for exploration programs, at different stages
Significant geochemical enrichment and quartz veining-breccia in sedimentary units along Ungarie granite contact zone
Confirmed outcropping of mineralized veins support IRGS model
Regional residual gravity mapping indicated the Central Lachlan Fold Belt granites is underlain by large gravity lows suggesting deep seated granite batholithic roots
Regional gravity gradients strike north/northwest
Secondary northeast/northwest structural orientations coincide with known Gold enrichment and mineralization
Lake Cargelligo lies to the south of the Erimeran Granite batholith which is surrounded by known sediment hosted
Au deposits
Magnetics indicates strike extensions to the Josephine Moulder Fault and potential repeat structures undercover as well as numerous magnetic anomalies prospective for large-scale IRGS mineralization.

Rock chip sampling shows excellent gold and silver grades:
Significant amount of historical surface soil and auger sampling done
Peak results 2.26g/T-Au, 2.25g/T-Ag, 11ppm Bi, 330ppb Te
Numerous, widespread, multi-element pathfinder anomalies
(Te–Bi–As, etc)
Pathfinder response, along geological contact, indicates strong support for IRGS-type mineralization
Very few geochemical anomalies tested with drilling, restricted to outcrop areas
Limited Drilling results show wide zones of IRGS mineralization
