Highlights
-
High grade gold intersected in reconnaissance AC drilling at Datatine
-
Gold anomalism at Datatine is present within in-situ laterite that overlies apparent bedrock hosted mineralisation
-
Geology and alteration at Datatine similar to the Jinkas Corridor
-
Significant discovery potential with the exploration model validated by recent AC drilling
-
Follow-up RC drilling at Datatine planned
Ausgold Limited (ASX: AUC) (“Ausgold” or “the Company”) is pleased to advise that the remaining assay results have been received from recent Air Core (“AC”) drilling at it 100% owned Katanning Gold Project (“KGP”). The AC drilling was designed to test the Company’s untested exploration
model and targeted two areas, Datatine and Jinkas West. At Datatine, the programme has been exceedingly successful with high-grade mineralisation intersected. No economic mineralisation was intersected in the wide-spaced reconnaissance AC drilling at Jinkas West. Significant results at Datatine that were previously announced in ASX release dated 05/05/2016 include (see also Table 1 ) :
-
22m @ 3.67 g/t (from 4m to the end of hole), including 4m @ 16.90 g/t from 4m in BSAC1343, and
-
17m @ 1.00 g/t (from 16m to the end of hole), in BSAC1344
Subject to the availability of funding, the Company has planned systematic follow-up drilling, consisting of:
-
RC drill testing of high grade intercepts at Datatine later this quarter (approximately 500m)
-
Wider AC drilling at Datatine during the September Quarter (approximately 5000m)
-
AC drilling of priority target areas over the wider KGP (approximately 8000m)

Ausgold’s Geology Manager, Miss Melanie Sutterby comments:
“The results of the AC program have been highly successful. The Datatine prospect is an exciting development with significant gold mineralisation intersected.
The recent drilling program has demonstrated proof of our exploration concept and Ausgold can now confidently advance further exploration programs.”

Drilling Program Results
The total drilling program at Datatine consisted of 112 AC holes for a total of 3312m testing a coincident gold-in-soil geochemical anomaly and interpreted geophysical target ( Figure 1 ).
These results have identified significant gold anomalism extending over 400m in strike, which appears to be open in all directions, including at depth ( Figure 2 ). The gold anomalism intersected in the AC drilling corresponds to existing coherent gold-in-soil anomalies and a prospective fold structure as interpreted from airborne magnetics ( Figure 3 ). Significant results are included in Table 1 .

Planned Follow-up Drilling
The assay and geological data derived from the AC drilling has assisted in modelling the major mineralised trends at the Datatine North target area. The aim of the planned RC drilling is to better define the lateral and vertical extents of this mineralisation.
The initial phase of follow-up RC drilling has been planned to commence in June. This program will comprise 5 RC holes for approximately 500m. A number of RC holes are designed to re-confirm the highgrade AC intercepts, while other holes will test down dip and approximately 50m along strike to the eastnorth-east.
Further reconnaissance AC drilling across priority targets ( Figure 3 ) is planned to commence in the September Quarter, in addition to further follow-up RC drilling, subject to availability of funding.
A Program of Works (POW) has been submitted and approved by the Department of Mines and Petroleum (DMP).

Other Activities
An assertive, multi-faceted exploration and development strategy will systematically identify, develop and progress new mineral resources, exploration targets and realise the value of the KGP asset.
Ausgold is engaging SRK Consulting (SRK) as part of its exploration and research strategy to target highgrade gold mineralisation at the KGP. Using these new geoscience concepts, initially developed with the assistance of SRK, has already enabled Ausgold to recognise the exploration and discovery potential at KGP. It is anticipated that the continuing development of these new geological concepts with SRK will give Ausgold a competitive edge in identifying further opportunities at the KGP.
Ausgold is also embarking on a Mineral Resource update for the White Dam deposit following the recently announced exceptional drilling results (refer ASX announcement “Drilling confirms high grade shoot extensions at KGP” dated 7/4/16).
In addition, a scoping study update is proposed which will include the Jackson and White Dam Mineral Resources. Market changes and recent drilling results at these deposits have improved their viability for inclusion in preliminary mining development studies.
Datatine Discovery Lead Up
The KGP is located 275 kilometres southeast of Perth and approximately 40km northeast from the wheat belt town of Katanning. Ausgold holds a dominant ground position in this relatively under-explored greenstone belt ( Figure 4 ), an area highly prospective for Archean gold deposits.
At the KGP, the conventional exploration paradigm favoured a porphyry or stratigraphic-style exploration model, where gold-bearing fluids migrated along porosity-permeability controls.
While pervasive pyrrhotite-pyrite alteration and minor quartz veining was observed, there was little emphasis placed on the significant role that structural controls played within these ore bodies. During a hiatus in exploration activity at the KGP between 2013 and 2015 a thorough re-interpretation using the data available (including open pit exposures, diamond core, drill logs, geophysical and geochemical datasets) revealed the complexity of controls on mineralisation and highlighted the presence of high grade pipe-like shoots.
Datatine represents a high priority target with a coherent geochemical anomaly and a coincident Jinkas magnetic “look-alike” geophysical signature.
The magnetic anomaly at Datatine is orientated east-west, rather than north-north-west, as at Jinkas. Historic drill holes at Datatine were drilled on an east-west orientation, which in light of the geophysical analysis was deemed to have been sub-optimal. The recent AC drilling was re-oriented on a north-south direction (335° azimuth) to intersect any potential mineralised structures.

| Sampling techniques |
Nature and quality of sampling (eg 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 (eg ‘reverse circulation drilling was used to obtain 1m samples from which 3kg was pulverised to produce a 30g 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 (eg submarine nodules) may warrant disclosure of detailed information. |
This Air Core (“AC”) drilling program consisted of 112 AC holes for 3312m. Drilling was on a nominal line spacing of 100m, 200m or 400m with hole spacing on a top-to-tail basis or nominal 80m spacing. All holes were drilled to blade refusal. Samples from AC drilling were collected a rig-mounted cyclone by bucket in one meter intervals. Sample material was placed directly on the ground from the buckets in rows of ten. A spear sample was taken from each bulk sample and composited to 4m, weighing to approximately 3kg.. Spear samples were taken as consistently full and level for each sample. An additional 1m end-of-hole (EOH) sample was taken for multi-element and gold assay. Sampling was undertaken using Ausgold’s sampling protocols and QAQC procedures in line with industry best practice. The 3kg AC composite samples were sent to ALS Laboratory in Perth. Samples were sorted, dried, crushed to 10mm, pulverised to -75µm and split to produce a 10g sub sample (charge) for aqua regia digestion and gold analysis by ICP- MS with a 1ppb lower detection limit (4,000 ppb upper limit). The EOH AC samples were prepared in the same manner but underwent a four acid digestion (total digest) and eventual multi- element analysis by ICP-OES and ICP-MS for 63 elements (Au, Ag, Al, As, Ba, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Hf, Hg, Ho, In, K, La, Li, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Pd, Pr, Pt, Rb, Re, S, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn, Zr). |

| 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. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Samples were mainly dry with some localised damp samples (95% of the Archean samples collected were dry). AC drill recoveries were visually estimated as a semi-quantitative range and recorded in the log. Recoveries were generally excellent (>90%), with reduced recovery in the initial near- surface sample and transported cover material. Drill cyclone and sample buckets were used to collect the 1m samples and cleaned between rod changes. In addition, the cyclone was generally cleaned several times during each hole (at the base of transported cover and the base of completed oxidation) and after each hole to minimise downhole and/or cross- hole contamination. The relationship between sample recovery and grade and whether bias has been introduced has not been investigated at this stage. |
| 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. |
All drill holes in the current program have been geologically logged to a level of detail to support the definition of geological domains appropriate to support Mineral Resource estimation and classification. The 4m composited sampling is not appropriate for mineral resource estimation. Representative rock chips from the EOH were collected in chip trays, and logged by the geologist at the drill site. Sample condition and degree of weathering were recorded qualitatively. No geotechnical logging is possible on AC samples. Lithology, weathering (oxidation state), structure, veining, mineralisation and alteration are recorded in detail using standard digital logging sheets and defined look up tables to ensure that all data is collected consistently. This data is logged using tablet computers. All data is validated by the logging geologist before being entered in an acQuire database. All drill holes are logged. |

AC composite samples and EOH samples are collected with a sample scoop. Dry samples below transported cover are riffle split to obtain representative 1m samples (submitted when anomalous). The samples were recorded as dry, damp or wet. Sample duplicates were obtained by repeating the composite sampling process.

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. |

| 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. |
The composite and EOH AC gold analytical technique used a 10g charge with an aqua regia digestion (partial digestion) which is considered appropriate for a first pass analysis of oxide-dominated material within the regolith intercepted by AC drilling. EOH AC samples underwent a four acid digest which is considered a total digest AC samples were collected at 1m intervals and composited into 4m samples using a scoop to sample individual metre samples. For QAQC samples, a sequence of matrix matched certified reference materials, commercial certified reference materials and blanks were inserted into the sample run at a frequency of approximately one in 14 samples. Sample sizes are considered to be appropriate for the style/texture of oxide and sulphide mineralisation at the Katanning Gold Project. CRM’s , field duplicates, blanks and standards were inserted approximately every 10m. Blank samples are inserted to check for contamination in field sampling, laboratory sample preparation and analysis. The blank material used should be below detection limits. The gold standards were sourced from Geostats Pty Ltd and RockLabs with gold certified values ranging between 0.10g/t and 0.80g/t. Standard reference materials are used to check accuracy and bias of the analytical method. The results were similar to the standard concentration for the specific standard. QAQC samples were monitored on a batch‐by‐batch basis. An assay batch is accepted if the blank samples are within the acceptable limits (5 times the lower detection limit) and the standards are within the + 3SD (standard deviations). One failed standard can cause rejection if the results around the failed standard are not in the normal grade range. A batch is also re‐assayed when assay results from two or more standards are outside the acceptable limits. The inserted blank materials did not show any consistent issues with sample contamination. |

| 100% of the gold standards assays were within acceptable limits with no low or high bias. The performance of field duplicates in AC samples is generally reasonable and the variations are related to the style of mineralisation. ALS also insert QAQC samples to internally test the quality of the analysis. These results are received with the assay results in each batch. The ALS QAQC included standards, blanks and duplicates for independent quality control. The results of the lab standards were also monitored on a batch to batch basis by the data geologist. The results did not show any issues with the laboratory. The sample sizes are considered to be appropriate to correctly give an accurate indication of mineralisation given the qualitative nature of the technique and the style of gold mineralisation sought. |
||
| 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. |
High standard QAQC procedures are in place (and will be audited), therefore repeatability issues from a QAQC point of view are not considered to be significant. Significant and/or unexpected intersections were reviewed by alternate company personnel through review of geological logging data, physical examination of remaining samples and review of digital geological interpretations. All assay data was accepted into the database as supplied by the laboratory. Data importation into the database is documented through standard operating procedures and is guided by acQuire import validations to prevent incorrect data capture/importation. Geological, structural and density determination data is directly captured in the database through a validation controlled interface using Toughbook computers and acquire database import validations. Primary data is stored in its source electronic form. Assay data is retained in both the original certificate (.pdf) form and the text files received from the laboratory. Data entry, validation and storage are discussed in the section on database integrity below. No adjustments to assay data were undertaken. |
| 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. |
Drill hole collars were located by handheld GPS. Expected accuracy is +/- 4m for easting, northing and +/- 10m elevation coordinates. This is considered acceptable for these regional style exploration activities The grid system is MGA94 datum, UTM zone 50. Elevation values were in AHD. Validated surveys are entered into the acQuire data base by data entry personnel. |

| 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. |
Sampling was conducted via AC on a nominal top-to-tail, 40m or 80m hole spacing and a line spacing of 100m, 200m or 400m. AC results reported are based on 4m composite samples for gold unless otherwise stated. |
| 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. |
Angled AC drilling (-60 towards 330 north) tested the interpreted north dipping stratigraphy perpendicular (based from field mapping and magnetic inversion modelling) minimising lithological bias. At this stage any primary mineralised structural orientation is unknown and no comment can be made The angled orientation of AC drilling may introduce sampling bias due to the unknown orientation of primary mineralisation/structures. This would be considered minimal as drilling coverage is essentially restricted to the overlying regolith and seldom penetrates fresh rock by more than a couple of metres. |
| Sample security |
The measures taken to ensure sample security. | AC samples are systematically numbered and placed in pre-printed (numbered) calico bags and placed into numbered polyweave bags which were tied securely and marked with flagging. Assay samples were stored at a dispatch area and dispatched, depending on the frequency of pickups and length of the program. Samples were shipped via Katanning Logistics directly to ALS in Perth. The sample dispatches were accompanied by supporting documentation signed by the geologist and showing the sample submission number, analysis suite and number of samples. The chain of custody is maintained by ALS once the samples are received on site and a full audit trail for every sample is available through the ALS’ Webtrieve application. Assay results are emailed to the responsible geology administrators in Perth and are loaded into the acQuire database through an automated process. QAQC on import is completed before the results are finalised. |

| 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. |
Reported results are all from 100% owned Ausgold Exploration Pty Ltd Mining Tenements (wholly owned subsidiary of Ausgold Limited), including E70/2928. Apart from reserved areas, rights to surface land use are held under freehold titles. Ausgold has entered into access and compensation agreements with freehold landowners that permit exploration activities. Bordering the eastern wall of the Jinkas open pit, there is a registered Aboriginal Heritage Site 5353 known as “Jinkas Hill”. No access for exploration or mining activities is allowed within this site unless a section 18 application to move/destroy an Aboriginal Heritage Site is submitted to the Department of Indigenous Affairs. The land is used primarily for grazing and cropping. The tenement is in good standing, and all work is conducted under specific approvals from the Department of Mines and Petroleum (“DMP”). |
| Exploration done by other parties |
Acknowledgment and appraisal of exploration by other parties. |
Gold mineralisation was discovered by Otter Exploration NL in 1979 at Jinkas Hill, Dyliabing, Lone Tree and White Dam after following up stream sediment anomalies. Between 1984 and 1988 Otter and related companies evaluated the region with several other explorers including South West Gold Mines and Minasco Resources Pty Ltd. In 1987 Glengarry Mining NL purchased the project and in 1990 entered into a joint venture with Uranerz who agreed on minimum payments over three years to earn 50% interest. Uranerz withdrew from the project in 1991 after a decision by their parent company in Germany to cease Australian operations. International Mineral Resources NL (“IMR”) purchased the mining leases and the Grants Patch treatment plant from Glengarry Mining NL in 1995 and commenced mining at the Jinkas deposit in December 1995. Ausgold understands the mine was closed in 1997 afterproducingapproximately20,000 oz ofgold from |

| the Jinkas and Dingo Hill open cuts at a head grade of approximately 2.4g/t. In addition, the mine closure was brought about by a combination of the low gold price of the time (<US$400/oz) and the inability of the processing plant’s comminution circuit to process hard ore from below the base of weathering. Reports from the period indicate that the ore bodies were reasonably predictable in terms of grade and continuity and appeared to produce consistent and reproducible results from grade control (Ravensgate, 1999). Great Southern Resources Pty Ltd (“GSR”) purchased the mining and exploration leases from IMR in August 2000. Ausgold entered into a joint venture with GSR in August 2010, and the mineral titles were transferred to Ausgold in entirety in August 2011. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The project includes two main deposit areas comprising Jinkas in the north, and Dingo in the south. The Jinkas area is further subdivided into a set of mineralised zones. The majority of the project area is overlain by residual clays with outcrop mostly limited to remnants of lateritic duricrust on topographic highs. Gold mineralisation is hosted by medium to coarse-grained mafic gneisses which dip at around 30° to 45° towards grid east (68°). These units represent Archaean greenstones metamorphosed to granulite facies. The mineralised gneissic units are interlayered with barren quartz-monzonite sills up to approximately 120 metres thick and are cross cut by several Proterozoic dolerite dykes that post-date mineralisation and granulite metamorphism. Gold predominantly occurs as free gold associated with disseminated pyrrhotite and magnetite, lesser pyrite and chalcopyrite and traces of molybdenite. Thin remnant quartz veins are associated with higher grade zones. |

||
| 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. |
All reported AC assays have been arithmetically length weighted. A nominal 0.1g/t Au lower cut- off is reported as being potentially significant in the context of the grassroots geological setting. Internal waste intervals (i.e. <0.1 g/t) to not exceed the width of a 4m composited sample. Higher grade intervals within larger intersections are reported as included intervals and noted in results table. No top-cut off grades have been applied until more assay results become available to allow statistical determination. |
| 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 (eg ‘down hole length, true width not known’). |
The geometry of any primary mineralisation is not known at present due to the early stage of exploration. The angled orientation of AC drilling may introduce some sampling bias (increasing the intercept width of flat lying or vertical mineralisation). All intersections are subsequently presented as downhole lengths. If down hole length varies significantly from known true width then appropriate notes are provided. |
