Underground Mining Study
Results have been received for the final 8 diamond core holes totalling 4,018 metres completing the 23 hole program (11,011 metres) targeting the Hangingwall and Porphyry zones below the Wyoming One open pit. This program is a follow up to the drilling completed late 2016 and August‐October 2017 (ASX announcements 19 January 2017 and 17 November 2017). The drilling confirmed continuity of the gold mineralisation in the Hangingwall and Porphyry zones, and demonstrated continuity of the systems to ‐ 200m RL, 300 metres below the planned base of the open pit.
The Hangingwall‐Porphyry contact mineralisation has a strike length of over 300 metres and is open to the south. Most of the mineralisation has a near vertical or steep east dipping orientation. Other structurally cross cutting zones exist within the porphyry, and while of limited strike length, these are often very high grade within broad low grade envelopes (eg WY971D 39.8m @ 1.62g/t Au, including 1.0m @ 26.2g/t Au). The vertical ore zones tend to average around 5 metres in true width, but can range from 1 metre to 20 metres wide.
The data will be incorporated into the resource model to form a basis for the underground mining study to be completed in Q1 2018.

ABOUT ALKANE ‐ www.alkane.com.au ‐ ASX: ALK and OTCQX: ANLKY
Alkane is a multi‐commodity company focused in the Central West region of NSW, Australia. Currently Alkane has two advanced projects ‐ the Tomingley Gold Operations (TGO) and the nearby Dubbo Project (DP). Tomingley commenced production early 2014. Cash flow from the TGO has provided the funding to maintain the project development pipeline and will assist with the pre‐construction development of the DP.
The NSW Planning Assessment Commission granted development approval for the DP on 28 May 2015 and on 24 August 2015 the Company received notification that the federal Department of the Environment gave its approval for the development. Mining Lease 1724 was granted on 18 December 2015 and the Environment Protection Licence was approved on 14 March 2016. Financing for this project is in progress and when completed should make Alkane a strategic and significant world producer of zirconium, hafnium and rare earth products with production targeted for 2019‐20.
Alkane’s most advanced gold copper exploration projects are at the 100% Alkane owned Bodangora, Wellington and Elsienora prospects. Wellington has a small copper‐gold deposit which can be expanded, while at Bodangora a large monzonite intrusive complex has been identified with porphyry style gold copper mineralisation. Gold and base metal mineralisation has been identified at Elsienora.

Laboratory Preparation – drill core was oven dried prior to crushing to <6mm using a jaw crusher, split to 3kg if required then pulverised in an LM5 (or equivalent) to ≥85% passing 75µm. Bulk rejects for all samples were discarded. A pulp packet (±100g) is stored for future reference Not applicable to this report Alkane (ALK) sampling techniques are of industry standard and considered adequate. DD – external laboratory duplicates used. Duplicate samples were recovered from crushed core samples and analysed separately. Sample sizes are industry standard and considered appropriate. |
| 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, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
Gold was determined using a 50g charge fused at approximately 1100°C with alkaline fluxes, including lead oxide. The resultant prill was dissolved in aqua regia and gold determined by flame AAS. For other geochemical elements, samples were digested in aqua regia with each element concentration determined by ICP Atomic Emission Spectrometry or ICP Mass Spectrometry. These additional elements were generally only used for geological interpretation purposes, are not of economic significance and are not routinely reported. Not applicable to this report or deposit. Commercially prepared Certified Reference Materials (CRM) and blanks were inserted at 1 in 50 samples. CRM’s were not identifiable to the laboratory. Field duplicate samples were inserted at 1 in 50 samples (alternate to CRM’s) for RC drilling programs. Laboratory QAQC sampling includes insertion of CRM samples, internal duplicates and screen tests. This data was reported for each sample submission. Failed standards result in re-assaying of portions of the affected sample batches. |
| 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. |
Drill data was compiled and collated, and reviewed by senior staff. External consultants do not routinely verify exploration data until resource estimation procedures are deemed necessary. Twinned holes have not been used as twinning provides verification only for extremely limited areas of a deposit. All drill hole logging and sampling data was hard keyed into Excel spreadsheet for transfer and storage in a Datashed database with verification protocols in place. |

| Discuss any adjustment to assay data. |
All primary assay data was received from the laboratory as electronic data files which were imported into Datashed database with verification procedures in place. QAQC analysis was undertaken for each laboratory report. Digital copies of Certificates of Analysis (COA) are stored in a central database with regular (daily) backup. Original survey data is stored on site. No assay data was adjusted. |
|
| 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. |
Drill holes were laid out RTK-DGPS. RC drill holes were surveyed using a single shot electronic camera at a nominal 30m down hole intervals. DD holes were surveyed at nominal 30m down hole during drilling to maintain drilling direction and then north seeking gyro at end of hole. All drill holes were originally laid out in MGA94 grid system to conform to reporting requirements for mine operations. The site is within an operating Mining Lease with excellent survey control. |
| 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. |
Drilling was spaced and oriented to intersect specific sites within the known mineralised envelope. The drill hole spacing has been shown to be appropriate by the visible continuity of mineralisation between drill holes. Sample compositing was not 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. |
Much care was given to attempt to intersect mineralisation at an optimal angle but in complex ore bodies this can be difficult. It is not thought that drilling direction will bias assay data however all attempt made to provide optimal intersection direction. |
| Sample security |
The measures taken to ensure sample security. |
All samples were bagged in tied numbered calico bags, grouped into larger tied polyweave bags and transported to the laboratory in Orange by Alkane personnel or courier. S ample submission sheets were delivered with the samples and also emailed to the laboratory. All sample submissions were documented via ALS tracking system and all assays were reported via email. Sample pulps were returned to site and are stored for an appropriate length of time (minimum 3 years). The Company has in place protocols to ensure data security. |
| Audits or reviews |
The results of any audits or reviews of sampling techniques and data. |
The Company does not routinely have external consultants verify exploration data. |

| Drill hole Information |
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole 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. |
See table in announcement No data has been excluded |
| 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. |
Reported results are – For uncut gold grades; Intercepts were defined (bounded) by 0.5g/t gold outer limit and may contain some internal waste; Only intervals grading ≥0.5 g/t gold were reported; Grades were calculated by length weighted average. Exploration results have been reported as length weighted average grades with internal high grade intercepts reported separately. No metal equivalents are reported. |
| Relationship between mineralisation widths and intercept lengths |
These relationships are particularly important in the reporting of Exploration Results. oIf the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. oIf it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
True width are variable due to the intersection angle but range between 50% and 70% of drilled width. |

| 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. |
A plan showing geology with drill collars and a composite long section are included with the announcement. |
| 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. |
Data relating to all drill holes where assays have been received at the time of reporting have been reported. |
| 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. |
No additional data is being reported. |
| Further work | The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). |
An assessment of mining the higher grade portions of the mineralisation by underground methods will be completed as part of a feasibility study. Additional drilling may be completed to compliment this assessment of mining resources below the open pit. The upper portions of the deposits are well constrained by drilling however the high grade structures remain open at depth. |
| Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
