OVERVIEW

Legend had a productive September 2017 quarter with diamond drilling at Area N, RC drilling at Areas N, E, F and O and an extensive regional MLTEM survey over seven targets in the southern part of the Rockford Project.

Analysis of assay and petrology results from drill samples at Area N revealed that the sulphide-rich mafic/ultramafic intrusive rocks encountered were too high in the system for the targeted nickel-copper mineralisation to be present. The conductors drill tested at Areas E, F and O were explained by pyrrhotite and graphite rich intervals within metasediments/granulites.

PROJECTS

Rockford - Fraser Range: Nickel-Copper Gold

Regional MLTEM surveys were completed over seven targets selected from interpretation of aeromagnetic and gravity data, resulting in the identification of new conductors at Areas Q, S and U.

Following the results from the diamond and RC drilling programmes at Areas N, E, F and O, Legend is undertaking a review of all data collected on the Project to date. The object of this review is to prioritise future field activities starting with the 3,000m aircore drilling programme scheduled to commence early November 2017.

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, three of which (E28/2675-2677) were recently granted on 14 August 2017.

Exploration activities during the quarter included: diamond/RC drilling at Area N, RC drilling at Areas E, F and O, and regional innovative moving loop electromagnetic (“MLTEM”) surveying over seven targets in the southern part of the Rockford Project. A summary of exploration completed is summarised below and discussed in detail in the body of this report, see Figure 1 for location.

  • Diamond and RC drilling at Area N targeting the N1 and N2 EM conductors

  • RC drilling at Areas E, F and O, targeting the E2, F1 and O1 EM conductors

  • MLTEM surveying over Areas P, Q, R, S, T, U, and V.

Area N

Exploration activities completed during the September 2017 quarter at Area N included:

  • Diamond drilling; two holes RKDD003-004

  • RC drilling; two holes RKRC006-007

  • Downhole electromagnetic (“DHTEM”) surveying; holes RKDD003-004 and RKRC007

  • Geochemical sampling; 406 drill samples for multi-element analysis

  • Petrological sampling; 22 samples for petrographic/lithological description.

The drilling programme at Area N comprised two diamond holes (RKDD003-004 for 1,350.4m) and two RC holes (RKAC006-007 for 338m), see Figures 1 & 2 and Table 1. The diamond holes were directly testing fixed loop electromagnetic (“FLTEM”) conductors N1 and N2, while the RC holes were drilled to test anomalous nickel-copper geochemistry returned in aircore drillholes RKAC068 and RKAC119, as well as the up-dip projection of the N1 conductor, see ASX announcements 9 May and 6 June 2017.

Drillhole RKDD003, testing conductor N1 intersected a package of felsic to mafic metasediments/granulites including a broad graphitic-sulphidic interval between 683m and 738m. Within this interval are two prominent pyrrhotite/minor chalcopyrite sulphide zones (1m and 2.8m respectively) with massive and matrix to net textures associated with pyroxene-rich lithologies.

DHTEM surveying in RKDD003 confirmed the graphitic-sulphidic interval (683-738m) as the source of the N1 conductor, but also identified a highly conductive offhole feature near the base of this interval. The offhole feature has a conductance of >30,000S, dimensions of <75m x 75m and is located ~20m below and southwest of the hole. This feature correlates closely with the 2.8m matrix sulphide zone hosted by pyroxene-rich rocks and interpreted as an extension of this interval, albeit with an increase in sulphide content.

Drillhole RKDD004, testing the N2 FLTEM conductor, intersected a thick package of mafic to felsic metasediments/granulites and thin mafic intrusives. Numerous thin graphitic-sulphidic intervals were noted between 483m and 532m, which correlate with the modelled position of the N2 conductor and confirmed by DHTEM surveying.

Full multi-element assay results for 164 drillcore samples from diamond drillholes RKDD003-004 were received, with the tenor of nickel and copper values as expected, and consistent with geological observations and logging, see Table 2.

RC drillhole RKRC007 (re-drill of abandoned RKRC006 due to poor ground conditions) was drilled to test anomalous nickel-copper geochemistry in aircore holes RKAC068 and RKAC119, and the up-dip projection of the N1 conductor, see Figure 2. The hole intersected a broad package of pyroxene-rich mafic granulite and ultramafic, similar to that observed in aircore holes RKAC068 and RKAC119. Assay results from these RC holes have been received and returned elevated nickel-copper values of similar tenor to the aircore holes and are summarised in Table 3 below.

Note: BOH – Bottom of Hole

DHTEM was completed in RKRC007 aimed at identifying possible offhole features and potentially assist with the interpretation/evaluation of the N1 conductor. Three inhole/offhole conductive intervals were identified and coincide with logged intervals containing variable amounts of graphite/sulphide. A very broad offhole feature centred below and north of the bottom of hole was also identified and interpreted to be related to the N1 conductor.

Results from 22 petrology samples from drillholes RKDD003-004 confirmed the presence of multiple mafic/ultramafic sill-like intrusions intruding the thick metasedimentary package with sulphidic-graphitic intervals. Significant mixing and assimilation of the sulphidic-graphitic metasediment with the intrusions has occurred and is a critical process in the potential formation of massive nickel-copper sulphide deposits, such as Nova-Bollinger. However, the intrusions at Area N are considered fractionated, high-level and low-Ni intrusions with any significant mineralisation occurring lower in the system.

The petrological information represents an important dataset, and when integrated with the lithogeochemistry, aeromagnetic and gravity data greatly assists the interpretation and geological understanding of Area N and the wider Rockford Project. Future exploration will be focussed on trying to identify the more nickel-rich parts of these mafic/ultramafic intrusions.

Regional RC Drilling

A regional RC drilling programme comprising three holes (RKRC008-010) for 768m, testing conductors at Area E (E2), Area F (F1) and Area O (O1) was completed during the quarter, see Figures 1 and 3 for location and Table 4 for hole details.

Drillholes RKRC008 (E2) and RKRC010 (O1) both intersected an intercalated package comprising metasediments/granulites containing broad graphite/sulphide intervals which adequately explain the targeted conductors. Similar lithologies were intersected in RKRC009 at F1, and while the amount of graphite-sulphide was less, it is felt that the conductor has been tested.

Results for the three RC drillholes returned anomalous iron and sulphur values from the logged graphite/sulphide (pyrrhotite) intervals as expected, along with elevated copper, zinc and silver values, see Table 5. No further work is warranted over these targets.

Regional MLTEM Surveys

Regional MLTEM surveys have been completed over seven new targets; Areas P, Q, R, S, T, U and V selected from interpretation of aeromagnetic and gravity data in the southern part of the Rockford Project, see Figures 1 and 4 for location.

The surveying utilised high power MLTEM and identified three significant bedrock conductors at Area Q (Q1), Area S (S1) and Area U (U1), see Figure 4 and Table 6.

U1 300-450S 1,500m x 350m 400-450m 50-600E

These three newly defined conductors now bring the total number of untested conductors across the Rockford Project to nine, namely D3, E1, J1-2, M1, N3, Q1, S1 and U1. An aircore drilling programme comprising a single traverse over each of the nine conductors is planned to provide lithogeochemical data and information on the depth and character of regolith.

Future Programmes

A 3,000m aircore drilling programme is planned over Areas D, J, Q and U, which contain EM conductors previously identified from regional innovative EM surveys, see Figure 1. This drilling will provide information on the regolith profile, basement lithologies and the lithogeochemical signature of the basement rocks, and assist with prioritising potential follow up RC/diamond drilling.
