OVERVIEW
The June 2017 quarter has been an active and productive quarter for field activities at the Rockford Project.
Legend’s innovative MLTEM surveys (over areas L, M, N and O) and FLTEM surveys (over areas E, M and N) have successfully resulted in identifying bedrock conductors for diamond drilling at N1 and N2 and for RC drilling at E2, F1 and O1. These drill programmes commenced in the last week of June 2017.

PROJECTS
Rockford - Fraser Range: Nickel-Copper Gold
The innovative MLTEM survey work is ongoing over selected areas in the south of the Project. Results from both the drilling and MLTEM surveys will be released as appropriate.
A 75 hole, 3,188m aircore drilling programme over selected traverses in the north of the Project was also completed during the reporting period. Assay results from this programme returned anomalous nickel and copper values at Area N, which supported the prospectivity of bedrock conductors N1 and N2. Furthermore, petrological analysis of a bottom of hole sample from RKAC068 revealed a hornblende-rich metamorphosed mafic rock, considered a highly favourable host rock for nickel-copper sulphide orebodies.

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 two granted exploration licences covering 238.5m[2] .
Exploration activities during the June 2017 quarter were initially focussed on the high priority Area N prospect, then extended over regional targets in the northern part of the Rockford Project, see Figure 1. A summary of exploration completed is summarised below and discussed in detail in the body of this report:
-
75 hole aircore drilling programme over north Rockford
-
Moving loop electromagnetic (“MLTEM”) surveying over Areas L, M, N and O
-
Fixed loop electromagnetic (“FLTEM”) surveying over Areas E, M and N.

Area N
Area N is characterised by a large folded and/or intrusive feature with generally low magnetic response closely associated with a 2.5 x 0.5km NE-SW trending gravity feature. MLTEM and FLTEM surveying was completed during April 2017 aimed at better defining the previously identified strong to moderate conductors (N1-N2) and allowing accurate geophysical modelling. The survey successfully defined the two conductors, which are summarised in Table 1 and shown on Figure 2.
| Table 1: Area N Conductor Description | Table 1: Area N Conductor Description | Table 1: Area N Conductor Description | ||
|---|---|---|---|---|
| Conductor | Conductance | Dimensions | Depth to Top | Plate Orientation |
| N1 | 6,000-12,000S | 850m x 300m |
500-550m | 75-850NW dip |
| N2 | 400-500S | 700m x 600m | 300-400m | 50-650E dip |
Two aircore drill traverses were completed at Area N aimed at providing bedrock information over the top of the N1-N2 conductors and gravity/aeromagnetic features, see Figure 2.

Figure 2: Area N - Aircore Drilling and FLTEM Conductors Over Gravity
The aircore traverse over the N1 conductor comprised 13 holes (RKAC065-073, 119-122) for 590m, intersecting a 200-300m wide central package of mafics flanked by felsic granulite, see Figure 2 & 3.
Aircore drillhole RKAC068 returned a result of 37m @ 0.1% Ni and 0.01% Cu from 24m to bottom of hole associated with a hornblende-rich metamorphosed mafic. RKAC119 was drilled 100m to the west of RKAC068, intersecting a similar lithology, returning 31m @ 0.09% Ni and 0.03% Cu from 20m to bottom of hole. In addition, RKAC120 (100m east of RKAC068) and RKAC073 (100m west

of RKAC119) returned elevated assays of; 1m @ 0.05% Ni and 0.03% Cu from 32m BOH, and 8m @ 0.02% Ni and 0.03% Cu from 32m respectively, see Figures 2 & 3.

Figure 3: Area N - Aircore Drill Section 6629000N
These results confirmed a +300m wide zone with anomalous nickel and copper values associated with a metamorphosed mafic, see Figure 3. Petrological analysis of this mafic unit indicated an original igneous composition rich in orthopyroxene/clinopyroxene, with subordinate plagioclase and olivine and a cumulate texture. The petrology also revealed the presence of supergene nickel minerals along with chalcopyrite (copper sulphide) further confirming it as a highly favourable host rock.
Importantly, the metamorphosed mafic unit correlates with the up-dip projection of the strong (6,00012,000S) N1 conductor (Figure 3) and is closely associated with the gravity feature and a localised aeromagnetic high.
-
Area N is considered a very high priority prospect with a summary of positive features given below: Strong (6,000-12,000S) FLTEM bedrock conductor defined at N1.
-
N1 conductor closely associated with a gravity feature and aeromagnetic high.
-
Aircore drillholes RKAC068 and RKAC119 over the up-dip projection of the N1 conductor intersected favourable metamorphosed mafic host rocks.
-
RKAC068 returned assay results of; 37m @ 0.1% Ni, 0.01% Cu from 24m to BOH including 4m @ 0.14% Ni, 0.01% Cu from 28m.
-
RKAC119 returned assay results of; 31m @ 0.09% Ni, 0.03% Cu from 20m to BOH including 4m @ 0.14% Ni, 0.06% Cu from 32m.
-
Elevated nickel and copper values in RKAC125 may be related to the N2 conductor.

North Rockford Aircore Drilling Programme
An aircore drilling programme comprising 75 holes (RKAC065-139) for 3,188m was completed during the quarter over the northern part of the Rockford Project. The drilling was undertaken over several targets (Areas L, M, N, O, see Figure 1) selected from aeromagnetic/gravity data and EM surveys, with the aim of providing information on the regolith profile, basement lithologies and the lithogeochemical signature of the basement rocks.
Table 2 below summarises all anomalous nickel (>0.03%) and copper (>0.02%) results from the 75 hole drilling programme.

Regional MLTEM Surveys
MLTEM surveys were completed over Areas E, L, M and O, along with FLTEM surveys at Areas E and M during April/May 2017. As a result of these surveys, geophysical modelling has defined two significant bedrock conductors E2 and O1, to go with the previously defined conductor F1, see Figure 4.
The three conductors are discussed in further detail below with conductor parameters summarised below in Table 3.

Conductor E2
Area E was originally selected for follow up MLTEM surveying focussed on a discrete 1.5km x 1.3km gravity high with associated strong magnetic response representing a complex fold closure. E2 is located on the far eastern side of Area E and associated with a subtle magnetic and gravity response. The moderate to strong bedrock conductor (4,000-6,000S) has a modelled size of 600m x 300m and a depth to top of source of 100-125m. RC drill testing of this conductor is planned.
Conductor F1
Area F is characterised by an elongate NE trending gravity high in the west and a more subtle gravity trend in the east. The aeromagnetics indicates a large open fold and a regional scale NW trending cross structure.
A MLTEM survey completed in December 2015 identified a NNE trending moderate bedrock conductor situated on the flank of the subtle eastern gravity trend. Modelling of the conductor indicated a depth to top of source of <125m, a conductance of 1,250-2,000S and a plate with dimensions of 800m x 800m. RC drill testing of this conductor is planned.
Conductor O1
Area O is characterised by a 3km x 1.5km folded and/or intrusive feature with low/moderate magnetic response. A NE-SW trending gravity ridge occurs in the eastern part of the prospect. MLTEM surveying identified a moderate to strong bedrock conductor (O1) in the SE.
Modelling of the conductor indicated a depth to top of source of 125-150m, a conductance of 2,5005,000S and a plate with dimensions of >300m x 300m. RC drill testing of this conductor is planned.
Current Drilling and EM Programmes
Diamond drill testing of conductors N1 and N2 at Area N, and RC drill testing of conductors E2, F1 and O1 commenced in the last week of the June 2017 quarter. It is planned to do downhole EM (DHTEM) follow up of all drill tested conductors. Results from the drilling will be released as appropriate.
Meanwhile regional MLTEM surveying is ongoing in selected southern areas of the Rockford Project.
