Further aircore drilling planned at Area D
Aircore drilling at Area D in November 2017 identified two drillholes, (RKAC151 and RKAC167) with anomalous nickel, copper and cobalt results from 4m composite samples at Legend’s Rockford Project in the Fraser Range of Western Australia. Resampling of these holes at 1m intervals was completed in December 2017 aimed at providing detailed geochemical information within the regolith profile.
Legend Managing Director Mark Wilson said, “These results are essentially a repeat of the earlier assays and confirm that the 4m composite sampling methodology that we are employing gives an accurate indication of nickel, copper and cobalt numbers. The new aircore programme is designed to investigate the anomalous geochemical footprint around holes RKAC151 and RKAC167 and more interesting magnetic/gravity features at Area D”.

Technical Discussion
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 was completed in December 2017 (RKAC151 over 60-111m and RKAC167 over 56-66m) aimed at providing detailed geochemical information within the regolith profile.
Full multi-element assay results from the 1m resampling in both drillholes have been received, showing 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.

Legend Mining Ltd – Aircore Drilling Programme Rockford Project – Area D JORC Code Edition 2012: Table 1
Section 1: Sampling Techniques and Data
Criteria |
JORC Code Explanation |
Commentary |
|---|---|---|
| Sampling techniques | • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
•Aircore drilling was undertaken on broad spaced traverses testing aeromagnetic and gravity targets. •The residual (non-transported) portion only of each drillhole was originally sampled as 4m composites to the end of hole, with a 1m bottom of hole sample also collected. All samples weighed 2- 3kg. •Resampling at 1m intervals has been completed over selected composited intervals returning anomalous Ni, Cu, Co results. •QAQC standards and duplicate samples were included routinely (approximately 1 each every 50 samples). •Samples were submitted to an independent commercial assay laboratory. •Au, Pt, Pd was analysed by fire assay with an ICP-OES finish. A four acid digest with ICP-MS finish was used for a multi-element suite including: Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pr, Rb, Re, S, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr. |
| Drilling techniques | • Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
•The aircore drilling technique was used, utilising a 85mm bit and completed by Drillpower. |
| Drill sample recovery | • Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. |
•Sample recoveries are visually estimated for each metre by the supervising rig geologist with poor or wet samples recorded in drill and sample log sheets. •The sample cyclone is routinely cleaned at the end of each rod (3m) and when deemed necessary. |

•Geological logging of all drillholes included; lithology, grainsize, texture, deformation, mineralisation, alteration, veining, colour, weathering. •Logging is qualitative and based on 1m intervals. Representative drill chips from the bottom of hole are retained in chip trays. •All drillholes were logged in their entirety. |
| Sub-sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
•All aircore drill samples were collected using a PVC spear or scoop as 4m composites (2-3kg). Other composites of 2m, 3m and 5m 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 mineralisation style sought and for the analytical technique used. |
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, |
•Aircore samples were analysed for Au by 50g fire assay with an ICP-MS finish, and for a multi-element suite by ICP-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. •Allsampleswere analysed byIntertek |

| • dip and azimuth of the hole • down hole length and interception depth • hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |

| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
•Weighted averaging based on sample interval has been used in the reporting of the aircore drilling results. •No short length high grade results were returned (therefore not included in aggregate intercepts) and no metal equivalent values have been reported. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
•The geometry of anomalous nickel- copper assays with respect to the aircore drilling angle and orientation is unknown. •All drillhole intercepts are measured downhole in metres. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
•Project location and drillhole location maps have been included in the body of the report. |
| Balanced reporting | • Where comprehensive reporting of all Exploration Results is not practicable, representative |
•All significant results are reported. |

| reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |

| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
•Detailed high quality aeromagnetic and gravity datasets have been used in the targeting of the aircore drilling. |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
•Further aircore drilling along with moving and fixed loop electromagnetic surveying is planned. |
