Legend field activities at the Rockford Project got into full swing this quarter with a five hole RC programme completed at Area D. Area D is characterised by coincident aeromagnetic and gravity anomalies with previous MLEM surveying identifying five significant bedrock conductors (D1-D5). The drill programme tested three of those conductors (D1, D2 and D4).
The lithologies intersected were typical of the Fraser Zone, which are considered highly prospective for Ni-Cu mineralisation.

PROJECTS
Rockford - Fraser Range: Nickel-Copper, Gold
Conductor D1 was explained by an intersection of 22m of graphite schist from 174m. At conductor D2 there was a 10m intersection of graphite schist from 141m, which does not explain the strength of the conductor and is not consistent with the modelled depth of the conductor which was 250m. A downhole EM survey is planned at D2 to look for offhole conductors. At conductor D4, no definitive conductor was intersected and a downhole EM survey is also planned. Four metre composite samples from all holes were sent for assay with results awaited.
Once results from the downhole EM surveys and the assays are received the next drilling programmes at Area D can be planned. Meanwhile integration of the new data obtained from the drilling with the existing data sets is assisting with future planning of aircore and ground EM programmes throughout the entire Project.

1. ROCKFORD PROJECT – (Fraser Range District) Nickel-Copper, Gold
The Rockford Project covering 2,939km[2] comprises eight contiguous granted exploration licences located in the highly prospective Fraser Range district of Western Australia (Figure 1). A large portion of the Project (2,530km[2] ) is the subject of a joint venture between Legend (70%) and Creasy Group (30%), with Legend operator and manager of the joint venture, (see LEG:ASX announcement 2 July 2015).
The project covers a strike length of 100km over a regional gravity high “ridge” associated with dense mafic/ultramafic intrusive rocks of the Fraser Zone, within the larger Albany-Fraser Orogen. The Nova-Bollinger deposit, which lies within the Fraser Zone, is situated on a similar tenor gravity ridge to that of the Rockford Project, see Figure 1.
Exploration completed during the quarter included; a five hole RC drilling programme testing three EM conductors at Area D and moving loop electromagnetic (“MLEM”) surveying over Area A North and South, see Figure 1.

RC Drilling Programme – Area D
A total of five RC drillholes (RKRC001-005) for 1,160m were completed at Area D, testing three strong-moderate conductors (D1, D2 and D4) previously identified by MLEM surveying, see Figure 2. Full drillhole details are provided below in Table 1.

The drilling has provided valuable geological information specific to Area D, and also marks the first RC drilling within the Project into the prospective Fraser Zone of the larger Albany-Fraser Orogen. Typical Fraser Zone lithologies were intersected including; pyroxene-rich mafic granulite, olivine/pyroxene-rich ultramafic, garnet/biotite felsic granulite and minor metasediment. This interlayered package follows the regional NE strike and has an overall steep NW dip. The rocks have experienced granulite facies metamorphism, however localised hydrothermal activity is evidenced by quartz veining and thin pegmatite units.
The presence of “dense and magnetic” mafic/ultramafic units intersected in the drillholes at Area D, and interpreted elsewhere in the Project, is consistent with the observed gravity and magnetic data. The information obtained from the drilling further supports Legend’s belief that the Rockford Project is highly prospective for Ni-Cu mineralisation associated with mafic/ultramafic intrusive bodies.
Descriptions of the three conductors (D1, D2 and D4) tested by the RC drilling are provided below.
Conductor D1
Drillhole RKRC004 (re-drill of RKRC001) was completed to a depth of 249m targeting a strong ~11,000S conductor at a modelled depth of 175-225m. The hole intersected a 22m interval of graphite schist between 174-196m, along with three other 1-3m thick graphitic units, within a package dominated by pyroxene-rich granulite. The graphite schist has fully explained the MLEM conductor.
Conductor D2
Drillhole RKRC005 (RKRC002 re-drill) was targeting a very strong ~17,000S conductor at a modelled depth of 250-325m and was completed to 284m. The hole intersected a 10m interval of graphite schist with clay alteration between 141-151m, followed by a 16m thick biotite schist with subordinate graphitic units. This graphitic unit does not match the modelled depth (circa 250m downhole) or the high conductance of the targeted conductor and the presence of a second deeper conductive body is interpreted. A DHEM survey is planned in RKRC005 to test for a second offhole conductive body as suggested by the modelling.
Conductor D4
Drillhole RKRC003 was completed to 268m targeting a moderate 1,000S conductor at a modelled depth of 175-225m. No definitive conductor was intersected in the drillhole, however between 190220m a package of predominantly mafic granulite containing 1-3% pyrrhotite/pyrite was observed. DHEM is planned to test for offhole conductors, which may represent higher accumulations of sulphide detected by the original MLEM survey.
Samples from all five drillholes were submitted for full multi-element analysis, with results pending.
The proposed drillhole at Area D Conductor D3 was not completed during this programme and will be assessed pending the results of the DHEM at Conductors D2 and D4 and receipt of assay results. The Conductor at Area F will be tested at a later date in conjunction with exploration activities in the northern part of the project.

MLEM Surveying
During the quarter MLEM surveying was completed over the untested targets from the 2015 programme at Areas A North and South. At Area A South a localised conductive feature was identified by the MLEM and followed up with a fixed loop electromagnetic survey (FLEM). Unfortunately the FLEM did not define a significant bedrock conductor and the feature is interpreted as a major N-S trending fault/shear zone. No further work is planned at these targets.
Future Programmes
-
At Area D, DHEM is planned at Conductors D2 and D4 testing for offhole conductors.
-
Assessment of assay results from RC drillholes RKRC001-005.
-
Planning of follow-up programmes at Area D pending results from the DHEM and assays.
-
A regional +5,000m aircore programme aimed at providing geochemical and geological information over selected targets based on aeromagnetic and gravity datasets.

Section 1: Sampling Techniques and Data
| Criteria | Commentary |
|---|---|
| Sampling techniques | RC drilling was used to obtain samples on 1m intervals. For each metre drilled, a 2-3kg rig split sample is collected from the cyclone in a calico bag with the remainder of the sample collected in a green plastic bag (20-40kg). All drillholes have been sampled as 4m composites and where anomalous values are returned the 1m rig split samples may be submitted for assay. QAQC standards and duplicate samples were included routinely (approximately 1 each every 50 samples). Samples were submitted to an independent commercial assay laboratory and analysed for; Au by fire assay and a multi-element suite including Ag, Al, As, Ba, Be, Bi, Ca, Cd, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, Tl, U, V, W, Y, Zn, Zr by ICP- OES/MS. Noresultsreceived to date. |

| Criteria | Commentary |
|---|---|
| Logging | Geological logging of all drillholes included; lithology, grainsize, texture, deformation, mineralisation, alteration, veining, colour, weathering. Logging is qualitative and based on 1m intervals which are sieved and retained in chip trays. Alldrillholeswereloggedintheirentirety. |
| Sub-sampling techniques and sample preparation |
No drillcore was collected. RC drill samples were collected using a PVC spear or scoop as 4m composites (2-3kg). Other composites of 2m and 3m and individual 1m samples were collected where required, i.e. bottom of hole. Both wet and dry samples were collected. The samples are dried and pulverised before analysis. QAQC reference samples and duplicates were routinely submitted with each sample batch. The size of the sample is considered appropriate for the mineralisationstyle sought andforthe analyticaltechnique used. |
| Quality of assay data and laboratory tests |
RC samples will be analysed for Au by 50g fire assay with an ICP-OES finish, and for a multi-element suite by ICP-OES/MS following a four acid digest. These assay methods are considered appropriate. QAQC standards and duplicate samples were included routinely (approximately 1 each every 50 samples). In addition reliance is placed on laboratory procedures and internal laboratory batch standards and blanks. |
| Verification of sampling and assaying |
Primary data was collected in the field using a set of standard logging templates and entered into a laptop computer. The data was forwarded to Legend’s database manager for validation and loading into the company’s drilling database. No validation or adjustment of assay results has been undertaken, asno assayresultshave been received to date. |
| Location of data points | RC drillhole collars are surveyed with a handheld GPS unit with an accuracy of ±5m which is considered sufficiently accurate for the purpose of the drillhole. All co-ordinates are expressed in GDA94 datum, Zone 51. Regional topographic control has an accuracy of ±2m based on detailed DTM data. |
| Data spacing and distribution |
Drillhole spacing is not regular or grid based, with the location of individual drillholes governed by targeting the position of modelled EM conductor plates. Drillholes are sampled as 4m composites and where anomalous values arereturned1msamplesmay be submittedforassay. |
| Orientation of data in relation to geological structure |
Drillholes were planned to intersect modelled EM conductor plates perpendicular to strike. |
| Sample security | Samples were placed in polyweave and/or bulka bags and delivered directly to the assaylaboratory. |
| Audits or reviews | Internal audits/reviews of procedures are ongoing, however no external reviews have been undertaken. |
