Alchemy Resources Limited ( ASX: ALY ) (“Alchemy”) is pleased to announce additional significant results received from the Phase 2 resource drilling within the West Lynn Nickel-Cobalt Project in the Lachlan Fold Belt, NSW, which forms part of the Heron Resources Limited ( ASX: HRR ) Farm-in Agreement ( Figure 1 ). The results confirm broad high grade nickel (Ni) - cobalt (Co) mineralisation within the laterite and saprolite profiles at both West Lynn and Summervale, and confirm and extend broad zones of alumina (Al2O3) immediately above the Ni-Co mineralised zone.
Phase 3 drilling is now underway, comprising infill and extension aircore drilling and 3 PQ triple tube diamond holes to allow for density measurements on the mineralised host rocks. Results from the Phase 3 drilling program are expected to facilitate the conversion of the existing West Lynn Nickel-Cobalt Exploration Target to a JORC Code 2012 compliant resource estimate.

The Phase 2 drilling program has also confirmed the potential to expand the known Ni-Co- Al2O3 mineralisation at both the Summervale and West Lynn prospects, with Alchemy’s drilling covering only about 10km of the 22km long West Lynn Serpentinite
West Lynn Prospect
All mineralised intercepts from the Phase 2 drilling (51 holes for 2,293m) at the West Lynn prospect (WLAC024 – 074) are included in Appendix 1. Significant Ni-Co results include:
-
25m @ 0.99% Ni, 0.06% Co from 36m (WLAC048)
-
28m @ 0.72% Ni, 0.04% Co from 32m (WLAC047)
-
21m @ 0.89% Ni, 0.04% Co from 39m (WLAC033)
-
22m @ 0.80% Ni, 0.04% Co from 45m (WLAC045)
-
23m @ 0.72% Ni, 0.04% Co from 35m (WLAC029)
-
10m @ 0.8% Ni, 0.07% Co from 11m (WLAC058)
High grade alumina (Al2O3) intercepts from the zone above the Ni-Co mineralisation include:
-
19m @ 18.7% Al2O3 from 8m (WLAC067)
-
18m @ 19.5% Al2O3 from 10m (WLAC069)

Ni-Co mineralisation at West Lynn is associated with variably limonitic and ferruginous clay, saprolite and weathered serpentinite units. The higher alumina grades are associated with pale cream to white clay units located immediately above the Ni-Co mineralisation. Both Ni-Co and alumina mineralisation at West Lynn continues to show good continuity, which is favourable for the forthcoming resource estimation work.

Summervale Prospect
All mineralised intercepts from the Phase 2 drilling (44 holes for 2,344m) at the Summervale Prospect (SV037 – 080) are included in Appendix 1. Significant Ni-Co results from the Phase 2 drilling include:
-
18m @ 1.0% Ni, 0.06% Co from 36m (SVAC069)
-
20m @ 0.9% Ni, 0.04% Co from 31m (SVAC039)
-
19m @ 0.9% Ni, 0.04% Co from 27m (SVAC040)
Broad, high grade alumina (Al2O3) intercepts from Summervale included 15m @ 22.9% Al2O3 from 33m in SVAC054. Sampling of the alumina rich layer above the Ni-Co rich clays is incomplete with remaining samples from this zone to be submitted with the Phase 3 drill samples.
Locations of the significant Ni-Co-Al2O3 intercepts from the Summervale Phase 1 and 2 drilling can be seen in Figure 5, and in selected cross sections below (Figures 6 & 7). Ni-Co mineralisation at Summervale is also associated with variably limonitic and ferruginous clay, saprolite and weathered serpentinite units. The higher alumina grades are associated with pale cream to white clay units located immediately above the Ni-Co mineralisation. Both Ni-Co and alumina mineralisation at Summervale also show good continuity, which is favourable for the planned resource estimation work.

The nickel and cobalt mineralisation at West Lynn is a direct result of weathering of the highly magnetic West Lynn Serpentinite unit ( red/white “peaks” in Figures 1, 2 & 5 ). The resulting metal rich clays are low in iron when compared to the typical Ni-Co laterite ore bodies formed in Western Australia.
Metallurgical sampling has commenced with samples to be shipped to Perth for recovery test work via the DNi Process™. The DNi Process™ is regarded as most efficient at extracting nickel and cobalt from laterites and is the first process to treat the entire profile of a laterite deposit (limonite and saprolite), leading to much better economic use of the resource. The process is based on simple chemistry with continuous, rapid tank leaching, achieving high nickel, cobalt, iron, alumina and magnesium oxide recovery rates. Over 95% of the leach reagent, nitric acid, is recovered and recycled, lowering production costs and efficiently reducing associated environmental issues. Plant Capex is lower than other hydrometallurgical processes, in part because the DNi Process™ does not require high pressures, high temperatures, or exotic processing plant construction materials.
For further information on the DNi Process™ refer to the Direct Nickel website (http://www.directnickel.com/).
Alchemy is highly encouraged by the nickel, cobalt and alumina results received from both the Phase 1 and Phase 2 drilling at West Lynn. The Company is looking forward to receiving additional ore grade results from the Phase 3 aircore program, and completing the resource estimation and preliminary metallurgical work on the Ni-Co-Al mineralisation over the coming months, with the resource estimate for the West Lynn Project now expected to be completed early 2019.

JORC Code, 2012 Edition – 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. |
The samples referred to in this Public Report were aircore (AC) drill samples, obtained using an ‘industry standard’ drill rig, drilling equipment and sampling practices. AC drilling was used to obtain 1m samples that were collected in plastic buckets via an industry standard cyclone. Each 1m sample was then split via a 3 tier splitter into large green plastic bags (87.5%) stored onsite as reference samples, and numbered calico bags (12.5%) for laboratory analysis. A grab sample was carefully obtained where material was too wet to be passed through the sample splitter. Both green bags and calico samples were weighed onsite for sample recovery recognition. The AC samples obtained are considered to be representative of the material drilled. |
| 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.). _ |
AC drilling was completed by McLeod Drilling using a MD150 drill rig with an on board 2 stage Airman Compressor (250 - 320psi / 700 - 850cfm) using an industry standard 90mm diameter aircore blade bit. |
| 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 and moisture content estimates were logged/recorded into spreadsheets by the supervising geologist. Each 1m sample (split green plastic and calico sample bag) was weighed after being collected. Thisgives an indication of recovery |

of drill material relative to all other 1m samples. No relationship is known to exist between sample recovery and grade, and accordingly no bias has occurred as a result of loss/gain of material. |
|
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. The total length and percentage of the relevant intersections logged. |
Geological logging was completed on all AC holes, with colour, weathering, grain-size, lithology, alteration, mineralogy, veining, textures/structure and comments on other significant features noted. Logging of mineralisation and veining is quantitative. All holes were logged in full. No judgement has yet been made by independent qualified consultants as to whether AC samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. 100% of relevant intersections have been logged. |
| 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. |
AC samples were riffle split if sample was dry, and carefully grab sampled by hand when wet. Sample preparation is considered appropriate with respect to quality of aircore sample collection. Sample sizes are considered appropriate for the style of mineralisation, the thickness and consistency of the intersections, the sampling methodology and the assay ranges for the primary elements analysed. |

Orange for analysis. Preparation of the samples follows industry laboratory best practice method PUL-21 involving logging of sample weights, drying the entire sample in an electric oven set at 105ºC+5ºC for several hours (drying time dependent on moisture content), then crushing the entire sample (>70% -6mm). A split of 2.5 to 3kg was taken and then pulverized to 85% passing 75μm using an Essa LM5 grinding mill. A representative sample was split and bagged as the analytical sample. Pulps were analysed using ALS method code ME-XRF12n designed for Nickel laterite deposits. The analysis uses XRF on fused disk. Laboratory QAQC involves the use of internal laboratory standards using certified reference material (CRM), blanks, splits and replicates as part of in-house procedures. Lab standards OREAS 45e, 195, 198 199, NCSDC73303, and SARM-5 were used as a standard for Ni-Co analysis. ALY used CRMs (Lab Standards) with a suitable range of values and blanks that were inserted every 40 samples. Standards used were OREAS 197, 198, 199 and 44e. Results indicate that assay values are within acceptable error limits. Duplicate samples were collected every 40 samples. Analysis of samples reveals that precision of samples is within acceptable limits. |
| Verification of sampling and assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
Reported drill hole intercepts are compiled by the Company’s Managing Director (MD) who is also the competent person. No twinned holes were drilled in the current drilling campaign. The original data is collected by qualified geologists and geo-technicians working under the supervision of a qualified geologist, and entered onto paper spreadsheets. |

| Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
A GPS was used to locate collar positions, with an expected +/-5m vertical and horizontal accuracy. DGPS collar pick-ups will be collected at the end of the Phase 1 and Phase 2 drilling. No down hole surveys were collected. The grid system used for all collar locations is the UTM Geocentric Datum of Australia 1994 (MGA94 Zone 55). The drill collar and down hole location accuracy is considered appropriate for this stage of exploration. |
| Data spacing and distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
At Summervale aircore holes have been drilled at 100m x 100m spacings over a 2.7km NE-SW trending strike length. At the West Lynn prospect aircore holes are spaced at 100m x 100m and 100m x 200m lines for a length of ~3.8km in a NNW-SSE direction. The distribution is considered sufficient to establish geological and grade continuity suitable for an inferred resource status. Sample compositinghas not been applied |
| Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Holes have been drilled vertically to achieve unbiased sampling of the flat lying lithologies and mineralisation. No orientation based sampling bias has been identified. |

| Mineral tenement and land tenure status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
Type - Exploration Licence (currently in good standing). Reference name – West Lynn. Reference numbers – EL8631. Location – 25km northwest of Nyngan, in north central NSW. Ownership – 100% Ochre Resources Pty Ltd, managed by Alchemy Resources (NSW) Pty Ltd. Overriding royalties - none The land is 95% freehold. No Wilderness Reserves, National Parks, Native Title sites or registered historical sites are known. No environmental issues are known. |

Acknowledgment and appraisal of exploration by other parties. |
Exploration work completed across the West Lynn and Summervale areas has been limited to exploration targeting gold and base metals since the late 1970’s. 38 RC holes were drilled by Anaconda in 1999/2000 to a max depth of 60m over West Lynn. These holes were successful in picking up nickel and cobalt mineralisation in lateritic clays associated with underlying serpentinites. Jervois applied for the ground in 2007 and began to explore for nickel-cobalt |

| mineralisation over magnetic anomalies related to underlying ultramafic units. AC drilling programs conducted over a period of 8 years has defined two prospects (West Lynn and Summervale) containing Ni- Co-Al mineralisation within clay and saprolite derived from the underlying weathered serpentinite units. |
||
| Geology | Deposit type, geological setting and style of mineralisation |
Deposit Type – Nickel-Cobalt Laterite Geological setting – The licence covers a north-south trending folded belt of serpentinised ultramafics known as the West Lynn Serpentinite surrounded by sediments of the Girilambone Group within the Girilambone-Wagga Anticlinal Zone. The linear orientation of the belt suggests emplacement along regional deformation or faults of Alpine-type origin (ophiolite). The West Lynn Serpentinite is derived from the alteration of a medium grained dunite intruded into the metamorphosed Ordovician Girilambone Group. The Girilambone Group is comprised of phyllites, quartz-mica and chlorite schists, quartzite, laminated siltstone (all with pervasive quartz veins) and conglomerates of Cambrian-Ordovician age; with numerous late Silurian to early Devonian intrusives of ultramafic to intermediate composition. Covered by Quaternary-aged alluvium. Style of mineralisation – Concentration of Ni-Co-Al within clays and saprolite derived from weathered serpentinite. |
| Drill hole Information |

o dip and azimuth of the holeo downhole length and interception depth o 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 (eg 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. |
Intercepts are from 1m individual samples. Any averaged intercepts are down hole length weighted averages (as per table in body of report). Lower cut off grades include 2000ppm for nickel intercepts, 200ppm for cobalt intercepts, and 15% for Al intercepts. No upper cut off grades have been used to calculate intercepts. |
| 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’). _ |
Due to the nature of the targeted mineralisation being flat lying, all drilling was vertical (-900), and subsequently all intercepts reported are downhole widths. |
| 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. |
||
| Balanced reporting |
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
Exploration results reported in Alchemy’s public announcements and this report are comprehensively reported in a balance manner. |
| 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. |
|
| Further work | The nature and scale of planned further work (eg 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. |
Phase 3 resource drilling aims to continue infill and resource extension aircore drilling and to drill 3 PQ triple tube diamond holes for density measurements of the various forms of mineralisation in the ore zones. The drilling ultimately aims to advance the existing West Lynn Nickel-Cobalt Exploration Target to a JORC Code 2012 compliant inferred resource estimate. Phase 4 drilling will focus on northern and southern extensions to mineralisation at both West Lynn and Summervaleprospects. |
