QUARTERLY REPORT
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
Exploration activities completed during the December 2021 Quarter at the Rockford Project included continued focused exploration on the Mawson prospect, as well as highly ranked regional targets. Systematic step-out diamond drilling continued to grow the Mawson intrusion to the north- east, intersecting mineralised intrusion as well as defining the architecture of the Mawson intrusion in relation to the country rock. The evolving understanding of the Mawson structural architecture has resulted in the potential identification of trap sites for massive Ni-Cu sulphide accumulations in this north-east zone. 3D model evolution utilising updated geophysical and geological modelling continues to drive focused exploration targeting, with the mineralised intrusive footprint growing significantly. In addition, a 3D seismic survey was completed by HiSeis Pty Ltd to define the architecture of the Mawson intrusion in relation to the stratigraphic package to a minimum 1000m below surface. Regionally, first-pass diamond drilling by Legend has been completed at highly ranked targets Hurley, Crean, and the new Northerly prospect. Aircore drilling across greater Mawson and regionally across prospective targets has been completed, with MLTEM survey completed across multiple new target areas of the Rockford Project (see Figure 1).

Mawson Prospect
3D Seismic Survey
HiSeis has completed the 3D seismic survey data acquisition phase at the Mawson Prospect (see Figure 1). Data processing has commenced, with delivery of final product is expected by February 2022.
The aim of the survey is 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 (See Figure 2). In addition, a more detailed survey on the western side of the survey area has been designed to test for a direct detection signature of Ni-Cu-Co sulphide accumulations at the Mawson discovery zone, given the shallow nature of mineralisation (<250m below surface).
On receival of the final results of this 3D seismic survey, Legend will conduct an intensive process of interrogation, including incorporation of existing geophysical, geological, geochemical, and structural datasets with the aim to define and rank new diamond drilling targets for the 2022 field season across the Mawson intrusion.

QUARTERLY REPORT
Diamond Drilling
Diamond drilling continued during December 2021 Quarter, with 9 holes completed (RKDD061 and RKDD073-RKDD080), resulting in a total of 21,202.4m drill metres completed for the 2021 field season (see Figure 1, Figure 3, and Table 1). Systematic step-out diamond drilling continues to grow the Mawson intrusion to the north-east, intersecting mineralised intrusion as well as defining the architecture of the Mawson intrusion in relation to the country rock. The evolving understanding of the Mawson structural architecture has resulted in the potential identification of trap sites for massive Ni-Cu sulphide accumulations in this north-east zone.
The 3D model driving predictive exploration at Mawson continues to evolve with new data and continues to be very accurate as a predictive tool for targeting interpreted fertile intrusion. The updated 3D constrained gravity model at this stage appears to have a high correlation for mineralised intrusion. To date, the mineralised intrusive footprint at Mawson extends over 1.6km in strike length. The northern most drill section completed suggests intersection of a new intrusion adjacent to the Mawson intrusion.
Future diamond drilling planning at Mawson will focus on continued definition of these mineralised intrusive bodies at depths below 500m based on the interpretation of the seismic data. Geological, structural, and geochemical datasets will be combined with seismic, gravity, magnetic, and DHTEM datasets to design our 2022 diamond drill programme to test targets for massive Ni-Cu sulphide accumulation.
