ROCKFORD PROJECT (Fraser Range District)
Nickel-Copper,Copper-Zinc-Silver, Gold
Legend's Rockford Project is located in the highly prospective Fraser Range district of Western Australia and considered prospective for mineralisation styles including magmatic nickel-copper, VMS zinc-copper-silver and structurally controlled gold.
The Rockford Project comprises 15 granted exploration licences (14 contiguous) covering a total area of 3,056km2 (see Figure 1). A detailed breakdown of ownership, area and manager is given below:
- Legend (100%) 206km2
- Legend (70%)/Creasy Group (30%) two JVs covering 2,192 km2 with Legend manager
- IGO (60%)/Creasy Group (30%)/Legend (10% free carry) JV covering 634km2 with IGO manager
- IGO (70%)/Legend (30% free carry) JV covering 24km2 with IGO manager
Activities continued during the June 2022 Quarter at the Rockford Project, with diamond drilling testing seismic targets at the lead Mawson Prospect, while regionally, innovative EM and aircore drilling continued to identify a new pipeline of prospective Ni-Cu targets.
3D model evolution utilising updated geological and geophysical modelling, including 3D seismic, continues to drive focused exploration targeting at Mawson. The aim of the seismic survey was to define the architecture of the Mawson intrusion in relation to the stratigraphic package, to a depth of investigation of a minimum 1000m below surface across a 6.5km2 area. Diamond drilling of select seismic features continues, with initial results supporting the application of seismic as a targeting technique in the Fraser Range.
Regionally, extensive datasets have continued to be expanded and interrogated to generate a new pipeline of Ni-Cu-Co sulphide targets. A 30,000m first pass aircore drilling continues across new and existing targets. Additionally, innovative MLTEM and FLTEM surveys continue across high priority targets at the Rockford Project.

only | Mawson Prospect | ||||
The aim of the seismic survey was to define the architecture of the Mawson intrusion in relation to the | |||||
stratigraphic package, to a depth of investigation of a minimum 1000m below surface across a 6.5km2 area. | |||||
The 3D seismic data supports the exploration model at Mawson, that a large intrusive source continues at | |||||
depth below drilling completed to date. 3D seismic reflectors clearly map the mineralised chonolith in drilled | |||||
areas down to 500m below surface, with the chonolith interpreted to extend below 500m, below the | |||||
use | Mawson fault, to a possible keel position at ~800m to 1,000m. This interpreted keel position is defined by | ||||
a complex set of reflectors and structural breaks, consistent with the seismic signature of the Mawson | |||||
discovery zone (see Figure 3). | |||||
RKDD081 was the first diamond drillhole to interrogate | |||||
the interpreted keel below the Mawson fault (see Figure | |||||
2 and Figure 3). Drilling conditions encountered resulted | |||||
in slower than anticipated drilling rates and a swing in | |||||
personalFor | the hole trace, with rotation, away from planned | ||||
trajectory. The drillhole largely intersected intrusive | |||||
suites and metasedimentary packages where predicted. | |||||
The lower zone of the target zone intersected various | |||||
mafic intrusive suites, including a heavily disseminated | |||||
gabbronorite intrusion at 840m downhole (see Photo 1). | |||||
Early interpretation of the intrusive suite intersected in | |||||
RKDD081 suggests the drillhole has tested an area | |||||
marginal to the main chonolith. Further data analysis and | |||||
additional drilling will aid in refinement of the initial | |||||
interpretation. Assay results are pending. | |||||
