-
Two separate mineralised intrusive bodies identified with anomalous nickel-copper geochemistry centred around RKAC151/183 and RKAC167
-
Anomalous nickel-copper-cobalt assay results confirmed by 1m sampling in RKAC151 and RKAC167
-
18 holes (1,326m) completed in ongoing 100 hole aircore drilling programme at Area D
OVERVIEW
The ongoing aircore drilling programme at Area D has delivered outstanding results for Legend shareholders with a threefold appreciation in the share price over the last two quarters. The key elements to this success are the reported anomalous nickel and copper drill results, the presence of sulphides within gabbronorite (the right host rock) and the identification of two separate mineralised intrusive bodies to date.
Legend believes the greater Area D (16km x 5km) has the potential to contain multiple such bodies and the focus of the current regional drilling programme is to test this belief. It is expected that this 8,000m aircore drilling will take several months to complete and results will be released when received ensuring a regular newsflow throughout this time.
PROJECTS
Rockford - Fraser Range: Nickel-Copper Gold
The results from this drilling will identify the rock types associated with the intrusives, thus assisting in the prioritisation of areas for our innovative moving loop EM surveys, which are planned in June/July 2018.

1. ROCKFORD PROJECT – (Fraser Range District) Nickel-Copper, Gold
Legend’s Rockford Project is located in the highly prospective Fraser Range district of Western Australia and covers a total area of 2,792.5km[2] , see Figure 1. The majority of the project (2,530km[2] ), comprising seven contiguous granted exploration licences, is the subject of a joint venture between Legend (70%) and Creasy Group (30%), with Legend operator and manager of the joint venture. The remaining 262.5km[2] is 100% owned by Legend and includes five granted exploration licences.
Exploration activities during the quarter focussed on Area D and included; petrology and 1m resampling of the previous (November 2017) drillholes RKAC151 and RKAC167 along with the completion of a further 18 aircore drillholes for 1,326m, see Figures 1 and 2. A detailed discussion of these results is provided in the body of this report.

Area D
Exploration activities completed during the March 2018 quarter at Area D included:
-
1m resampling of Ni-Cu-Co anomalous drillholes RKAC151 and RKAC167 (drilling completed in November 2017)
-
Aircore drilling; 18 holes RKAC181-198 for 1,326m
-
Geochemical results returned for 61 samples from aircore drillholes RKAC181-183
-
Petrographic examination of bottom of hole sample in RKAC167 and RKAC183
-
57 samples from aircore drillholes RKAC184-198 submitted for assay, results pending
Aircore drilling at Area D in November 2017 identified two drillholes, (RKAC151 and RKAC167) with anomalous Ni-Cu-Co results from 4m composite samples, (ASX releases 11 and 18 December 2017). Resampling of these anomalous intersections at 1m intervals (RKAC151 over 60-111m and RKAC167 over 56-66m) revealed a very close correlation to the original 4m composite sampling, see Table 1 for comparison. Importantly, the presence of anomalous copper values associated with the nickel was confirmed, reinforcing the prospectivity of Area D.

Aircore drilling continued during the March 2018 quarter at Area D with a further 18 holes (RKAC181198) for 1,326m completed. The drilling comprised 200m infill drilling adjacent to the Ni-Cu-Co anomalous drillholes RKAC151 and RKAC167, aimed at defining the extent of the geochemical footprint, see Figure 2. Samples from all 18 drillholes were submitted for multi-element laboratory analysis, with results from RKAC181-183 received and the remaining 15 holes pending.

Figure 2: Area D Aircore Drillholes on Aeromagnetics
RKAC151 Infill Drilling
Drillholes RKAC181, 182, 183 and 186, were drilled 200m west, east, north and south respectively of RKAC151, aimed at following up the highly anomalous Ni-Cu-Co intersection of; 47m @ 0.30% Ni, 0.11% Cu, 0.03% Co from 64m to EOH.
RKAC183 (200m north of RKAC151) intersected disseminated sulphides comprising pyrrhotitechalcopyrite-pentlandite within the same cumulate textured olivine gabbronorite host rock observed in the bottom of RKAC151, see Photo 1. This hole confirms that the 47m Ni-Cu-Co intersection associated with abundant iron-rich clays in RKAC151 is directly related to weathered sulphides within a gabbronorite intrusive.
Multi-element results for 1m samples from RKAC183 were received and returned the following intersection:
RKAC183 - 14m @ 0.37% Ni, 0.43% Cu and 0.03% Co from 72m to end of hole Incl. 2m @ 0.46% Ni, 1.44% Cu, 0.04% Co from 77m
This intersection is considered highly significant for several reasons:
-
The host rock is a cumulate textured olivine gabbronorite – a favourable host for Ni-Cu mineralisation, i.e. Nova host rock.
-
Confirms the presence of a Ni-Cu sulphide bearing mafic/ultramafic intrusive body.
-
The anomalous copper and silver values directly associated with the nickel values.

Drillhole collar details provided in Appendix 1.
Holes RKAC181, 182 and 186 also intersected olivine gabbronorite in the bottom of hole, however no sulphides were observed. The drilling around RKAC151 and 183 has broadly outlined the favourable gabbronorite host over an area of +600m x 200m, with a central “sulphidic” zone in the order of +200m x +100m. Further evaluation of the extent of the intrusive is planned.

RKAC167 Infill Drilling
Recent petrography from a RKAC167 bottom of hole sample identified the bedrock host as a pyroxene-rich gabbronorite cumulate with minor oxidised sulphide. The presence of the oxidised sulphide explains the previously received anomalous intersection of 10m @ 0.09% Ni, 0.09% Cu, 0.01% Co from 56m to EOH and increases the prospectivity around RKAC167.
Drillholes RKAC188, 189, 191 and 192, were drilled 200m north, south, west and east respectively of RKAC167, intersecting the same gabbronorite host along with minor oxidised sulphides. Assays for these drillholes are pending.
The aircore drilling at Area D to date has identified two separate mafic/ultramafic bodies with anomalous nickel-copper geochemistry centred around RKAC151/183 and RKAC167. Legend believes that the greater Area D region has the potential to contain multiple mafic/ultramafic bodies, as evidenced by the aircore drilling and aeromagnetic/gravity data, significantly increasing the prospectivity of Area D and the entire Rockford Project.
Future Programmes
-
Complete further infill drilling around RKAC151 and 183 to define the extent of the anomalous Ni-Cu-Co footprint.
-
Undertake additional drill traverses over other aeromagnetic and gravity features at Area D targeting mafic/ultramafic bodies.
-
Results from the aircore drilling will be used to assist design of follow-up MLTEM surveying.
