PROJECTS
Rockford - Fraser Range: Nickel-Copper Gold
The anomalous nickel-copper-cobalt assays in hole RKAC151 are a similar tenor to the aircore assays reported by Sirius Resources NL prior to the discovery of the Nova orebody in July 2012. The results from hole RKAC167, 1.6km from hole RKAC151, begins to give a sense of the potential scale of this anomalous footprint.
The subsequent petrology report which identified the host rock of the nickel-copper-cobalt anomalism in RKAC151 as an olivine-rich gabbronorite is also viewed as significant, as this is the host rock of the Nova orebody.
Legend is now awaiting the results of assays from the individual 1m samples, and an analysis of the iron rich clays and goethitic materials in hole RKAC151 to better understand the character of the nickel-copper-cobalt anomalism to assist in detailed planning of the next field programmes.

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 an aircore drilling programme with associated geochemical and petrological sampling, see Figure 1. A detailed discussion of the results is provided in the body of this report.

Area D
Exploration activities completed during the December 2017 quarter at Area D included:
-
Aircore drilling; 41 holes RKAC140-180 for 3,494m
-
Geochemical sampling; 153 drill samples for multi-element analysis and lithogeochemistry
-
Petrological sampling; bottom of hole (“BOH”) sample from RKAC151 for petrographic and lithological description.
An aircore drilling programme comprising 41 holes (RKAC140-180) for 3,494m was completed over Area D during the December 2017 quarter. The drilling was undertaken at 400m intervals along a 7.6km long E-W baseline and three N-S traverses, see Figure 2 and Appendix 1. The drilling intersected a range of bedrock lithologies including mafic intrusives and mafic to felsic granulites, all overlain by a thick profile of transported cover and saprock/saprolite.
A total of 153 drill samples, including composite and BOH samples were submitted for full multielement analysis. Drillholes RKAC151 and RKAC167 returned significant nickel, copper and cobalt results and are discussed further below.

Petrological examination of the BOH sample in drillhole RKAC151 has identified the host rock as a weathered olivine-rich gabbronorite orthocumulate (Photo 2), which is a favourable host rock for nickel-copper mineralisation. The peak nickel value of 0.40% Ni cannot be fully explained by nickelin-olivine, when related to the amount of olivine originally present in the gabbronorite, however the value can be explained by the weathering of primary nickel sulphides. The significance of this host rock is further enhanced by the anomalous copper values associated with the nickel assay results.

The petrology also identified minor amounts of a variety of copper minerals including; chalcocite, digenite, chalcopyrite and thin veinlets of native copper, thus explaining the anomalous copper assays. The presence of chalcocite suggests chalcocite-blanket weathering, where chalcocite has replaced pyrrhotite dominated Fe-Ni-Cu magmatic sulphides. This interpretation is supported by the presence of extensive Fe-rich clay development and goethitic material (up to 34.4% Fe) throughout the 47m interval of anomalous Ni-Cu-Co mineralisation, see Photo 1.
The prospectivity of RKAC151 is further enhanced given its location some 400m SE of diamond drillhole RKDD002, which was drilled in July 2016. RKDD002 intersected minor disseminated pyrrhotite/chalcopyrite/pentlandite at 626.8m downhole with petrological analysis indicating a magmatic origin for these sulphides in a cumulate textured olivine bearing ultramafic. Whilst a possible link between the anomalous Ni-Cu geochemistry in RKAC151 and Ni-Cu sulphides in a favourable host rock in RKDD002 is still interpretative, the prospectivity of Area D has been significantly increased by the recent aircore programme.
Drillhole RKAC167 returned an anomalous nickel, copper and cobalt intersection of: 10m @ 0.09% Ni, 0.10% Cu and 0.01% Co from 56m to end of hole. Whilst the nickel tenor is less than in RKAC151, the elevated copper and associated MgO are positive geochemical factors. This hole lies 1.6km to the SSE of RKAC151 and given the broad spacing of drilling to date, further highlights the potential of the prospect.
Table 2 below provides all Ni, Cu, Co and MgO assay results from RKAC167 including composite samples (56-66m) and a BOH sample (65-66m).

The anomalous intersection in RKAC167 is associated with a logged pyroxene-rich mafic and coincides with a 600m circular feature with elevated magnetic response centred within a larger 2km circular magnetic low, see Figure 2. There are several similar untested magnetic features throughout Area D, interpreted as possible intrusives, and require follow up exploration.
Future Programmes
-
Assays awaited from additional sampling at 1m intervals over the entire anomalous intersections in drillholes RKAC151 and RKAC167.
-
Results pending from analysis of Fe-rich clays and goethitic material in RKAC151 to assist understanding the character of the anomalous Ni-Cu-Co.
-
Further BOH sample petrology from Area D aircore drillholes to assist with bedrock rock identification.
-
Further evaluation of previously identified EM conductors at Areas D, J, Q and U.
