DIAMOND DRILLING AT KALPINI INTERSECTS HIGH GRADE GOLD MINERALISATION
KalNorth Gold Mines Limited (ASX:KGM) is pleased to advise that a five hole diamond drilling program completed in April at its 100 percent owned Kalpini Resource Project, located 60km to the north east of Kalgoorlie, intersected several encouraging narrow high grade gold mineralisation that supports the existing resource model .
The first round of drilling completed at the Kalpini Project since July 2012 has returned high grade gold results of:
• [email protected] from 117.5m downhole
Including [email protected] from 117.5m downhole
• 0.6m @10.7gpt from 46.5m downhole
• 1.3m @ 4.64gpt from 75.4m downhole
• 0.3m @ 14.3gpt from 112.1m downhole
• 0.6m @ 7.8gpt from 120.7m downhole
Intersections all located within the previously outlined Gambia-Camelia resource zone and give support to the existing interpretation and model
Drilling designed and targeted the stacked
narrow flat dipping quartz arsenopyrite breccia lodes proximal to existing drilling to improve understanding of the lode geometry and grade in an area previously evaluated with reverse circulation drilling.
Drilling confirms the nature and style of mineralisation which has a strike length of approximately 900m hosted within a layered gabbro.
Future work planned to update resource
model guided by recent drilling and report under JORC 2012.

About Kalpini Gold Project
The company's wholly owned Kalpini project is located some 60kilometres to the north east of Kalgoorlie and 23kilometres east of the Lindsays gold project where the company commenced open pit mining in January 2013, but suspended operations some 7 months later. The Kalpini project is centered on the historical Atlas gold workings which were operating in the early 1900's, but also the smaller nearby Camelia and Gambia prospects. Substantial reverse circulation (RC) and minor diamond drilling by the company at Kalpini during the period 2009-2012 supported the delineation of a mineral resource estimate (JORC 2004 Compliant) of 4.6Mt @1.7g/t Au for 255, 600oz ( refer ASX announcement dated 24 October
2012). The resource is covered by a single granted Mining Lease and is linked to Saracen Mineral Holdings
(ASX:SAR) Carosue Dam haul and access road 5.5km to the north by a granted miscellaneous licence, which can be used as a future haul road route if required. In March 2013 the company had announced (refer ASX announcement dated 20 March 2013) Kalpini would be its second open pit mining operation focussed on the Gambia Camelia zones, but this development was stopped due to the financial impact on the company by the early suspension of mining at Lindsays.
The company re initiated exploration at Kalpini in April 2015 and completed a five hole programme of infill RC precollared diamond holes along the Gambia-Camelia Trend (Figures 1&2). An aggregate 508m was drilled in five holes, four of which were new holes, the fifth being a re-entry of a hole drilled in 2012 (KPDD009-012, KPRCD371). The programme was specifically designed to provide further geological and structural controls on the flat dipping mineralisation to then support future upgrading of the resource estimate to JORC 2012 compliance. Significant (>1.0g/t Au) are tabled in Table 1 and the assay results received coupled with the structural data interpreted from the drill core confirm the flat dipping high grade nature of the lodes at Gambia and Camelia with the new information providing confidence in the current geological interpretation (Figures3&4).
The Gambia Camelia trend had been previously evaluated predominantly via reverse circulation (RC)
drilling over a strike length of approximately 900m and to a depth of 120m from surface and to a nominal
25m(N-S) by 20m(centers) drill pattern. An additional six diamond drill holes were completed in mid 2011 to along the trend to provide structural information and the style of gold mineralisation.
Gold mineralisation along the Gambia-Camelia trend has been defined over a 900m strike length and confined to multiple stacked narrow (0.5-3m) high grade flat dipping lodes hosted within gabbro. The lodes are characterised by arsenopyrite-sericite-carbonate quartz breccia's that have a limited leucoxene- chlorite-carbonate alteration halo in the host gabbro. Arsenopyrite content is variable but in the high grade lodes can be in the range 1-3%. Importantly, all drilling along the Gambia-Camelia trend has focussed on the flat dipping lodes which are focussed in the central portion of the gabbro, with no drilling targeting the contact with the intermediate volcanoclastic rocks. Both the hanging and footwall contacts of the gabbro may provide the locus for shear hosted gold mineralisation, the flat narrow high grade lodes
being perhaps brittle link lodes.

The recent drilling campaign at Kalpini is part of the company's strategy to realize value from its existing resource base through development. The information from the recent drilling will be incorporated into the existing Kalpini resource model to support reporting to JORC 2012 compliance. Resource modelling and targeting for additional styles of gold mineralisation will be commenced in the September 2015 quarter.
KalNorths Executive Director Lijun Yang commented "the high grade intersection from the Kalpini drilling confirms the modelled high grade, flat dipping mineralization along the Gambia Camellia trend. The completion of the planned updating of the resource model to JORC 2012 will form the basis for considering development strategies for the Kalpini project.

SECTION 1: SAMPLING TECHNIQUES AND DATA
Criteria
|
JORC Code Explanation
|
Commentary
|
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 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 (eg submarine nodules) may warrant disclosure of detailed information.
|
• Five angled RC precollared diamond holes drilled totalling 508m. Diamond core holes drilled using NQ2 sized rods. Half core cut, and samples collected at varying intervals based on geological logging and sample length varied from a minimum of 0.31m to a maximum of 1m. Due to nature of the mineralisation intervals less than 1m intervals were collected through the interpreted ore zone and standard 1m length intervals sampled in geological intervals adjacent to the ore zone. Each drill hole location (Easting and Northing)
was surveyed by Differential GPS by Cardno Surveys from Kalgoorlie. Detailed recording (logging) of collar, drilling, survey, lithology, and sample information was completed as necessary for each drill hole.
|
Drilling techniques
|
• Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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).
|
• Reverse Circulation (RC) drilling was used to complete precollars for each diamond drill hole by Raglan Drilling Contractors. RC face-sampling hammer bit achieved

|
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 report grades have been length
weighted. High grades have not been cut. A lower cu off of 1gpt Au has been used to identify significant results.

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').
|
• All results are based on down-hole metres.
• Structural logging of the orientated drill core has confirmed the nature and geometry of the mineralisation and the geology is depicted in the figures attached to this announcement.
