14 September 2016
Drilling to start next week to target resource extensions and repetitions at key projects in WA’s Mt Ida gold belt
Areas being targeted sit immediately adjacent to Eastern Goldfields’ high‐ grade Mt Ida underground mine
Highlights
-
Program of Works (POW) lodged for drilling at four prospects within Latitude’s Quinn Hills and Mt Ida South projects
-
Drilling to start next week with 2,500m ‐3,000m planned; Strike Drilling awarded the contract
-

-
Program expected to take ~three weeks with assays to follow shortly after
Latitude Consolidated (ASX:LCD) is pleased to announce that it is set to start drilling within a week at its Quinn Hills and Mt Ida South projects in WA’s rapidly emerging Mt Ida gold belt.
The Program of Works (POW) application for exploration programs at these neighbouring projects within WA’s North Eastern Goldfields have been lodged with the Department of Mines and Petroleum and Strike Drilling has been awarded the contract to undertake the RC drilling.
The drilling program comprises 25‐30 holes for a total of 2,500m ‐ 3,000m. It will target strike extensions and repetitions of known mineralisation on four prospects on the Quinn Hills Project and Mt Ida South Project areas.
A recent review of the existing surface geo‐chemistry, geo‐physics and drilling databases has identified numerous opportunities to extend the known zones of mineralisation and to build on the current Mineral Resource of 1.24mt @ 2.5g/t for 97,300 Oz (Measured, Indicated and Inferred) across the Quinn Hills and Mt Ida South project areas (see Table 1). The Mineral Resource statement is presented in Table 1 and has been classified in accordance with the JORC Code (2012).
Upon completion of its recently‐announced acquisition of the Mt Ida South gold project (see ASX release dated September 8, 2016), Latitude will hold 250sqkm in the Mt Ida belt.
The Company’s tenements host extensive known mineralisation, prospects which have not been followed up and numerous walk‐up drill targets.
They also surround the high‐grade underground mine owned by Eastern Goldfields (ASX: EGS). Eastern Goldfields has announced that it aims to develop a processing hub at Mt Ida.

A summary of Latitude’s impending drilling programs is provided below.
Quinn Hills Projects
Matisse (5,300 Oz @ 1.63g/t Au)
Eight RC holes totalling 750m are planned for the Matisse prospect. A resource covers the Matisse area. Mineralisation wireframes for this resource have been generated along a strike of approximately 200m. A review of the existing drilling shows that anomalous zones have been intersected in drilling 200m north and 100m south along strike from the resource wireframes. Sampling of these holes was predominantly undertaken using 4m or 5m composites which has effectively diluted the grade of the typically narrow (2‐3m) high grade zones. Planned drilling will target the north and south extensions with one‐metre sampling being undertaken to accurately assess the presence of narrow mineralised zones.
Quinn Hills (3,900 Oz @ 5.74g/t Au)
Seven RC holes totalling 770m are planned for the Quinns prospect. A resource covers the Quinn Hills area. Mineralisation wireframes for this resource have been generated along a strike of approximately 200m. A review of the existing drilling shows potential extension to the south and at depth of the main mineralisation. A parallel zone to the west of the main zone has been identified in historical drilling and planned drilling will test the continuity of this zone. Two lines of deep widely spaced holes exists to the south west of the main zone of mineralisation. These holes have intersected multiple narrow high‐grade zones with apparent continuity. The planned drilling will reduce the spacing on section to confirm the continuity of these zones.
Quinn Hills South
The Quinn Hills South area is an early stage exploration prospect. Existing auger sampling has identified an anomalous zone approximately 600m long and 100m wide. Geologically the anomaly is situated in favourable host rocks (mafic and ultramafic lithology’s) adjacent to a major north‐ south structure (Ballard Shear). The most prospective area for gold mineralisation on the eastern side of the project area occurs along the western edge of this structure. Two RC holes for a total of 240m have been planned to test the anomaly at its widest point in the north and where some surface indication of mineralisation has previously been intersected in shallow RAB drilling.
Mt Ida South Projects
Spotted Dog North and South (15,200 @ 1.87g/t Au, 5,100 @ 2.20g/t Au) and Tim's Find (30,900 Oz @ 2.54 g/t Au)
Six holes for a total of 610m are planned to cover the Spotted Dog and Tim’s find deposits. Resources cover both of these zones of mineralisation which run parallel to each other but are hosted in different lithologies. Drilling on the Spotted Dog trend is aimed at testing the approximately 1km gap which exists between the north and south zones. Should this drilling and subsequent drilling prove continuity, there is the potential to close this gap adding an additional 1km to the existing strike of this zone. Step out drilling to the north and south of Tim's Find is planned to extend the strike of this mineralisation.
It is expected that the drilling will be completed by mid‐late October and the first assay results should follow soon after that.

Notes on Mineral Resource
The deposits and nearby prospects are located in the Archaean Yilgarn Greenstone Belt of WA, more specifically within the northern portion of the Mount Ida Greenstone Belt forming the eastern limb of the regional south plunging Copperfield Anticline. The geology comprises Archaean mafic to ultramafic lithologies bounded by granitic intrusions, and the region has been metamorphosed to lower amphibolite facies. A major shear zone, interpreted to be the Zuleika Shear, intersects the eastern part of the project area. Much of the project area is covered by colluvial and alluvial deposits, with thickness ranging from <1m to tens of metres. Gold mineralisation in the area is associated with quartz veining +/‐ sulphides within sheared ultramafic and mafic units; along the Zuleika Shear gold is often found in quartz/pyrite lodes which are typically enveloped by tremolite schist, within intensely sheared amphibolites.
The Mineral Resources are located in an historical mining area, with open cut mines, costeans and underground workings prevalent. Geological exposure in these were used to guide the geological interpretation, with drill holes used to support the interpretation below the depths of mining. Reverse circulation (RC) and diamond drilling (DD) were used estimate grades into the Mineral Resource estimate. Aircore drilling was also used to assist with the geological interpretations for the mineralisation and weathering domains. No alternative interpretations were considered. Geological intercepts guided the geological interpretation, with the grade domains constrained by a grade envelope, based upon assayed Au (g/t) grades. Geological continuity was observed in the open cut geological exposure and influenced the interpretation of the mineralisation models.
Reverse Circulation and Aircore drilling were carried out by WildAcre (a previous holder of the leases) over several drilling campaigns from 2010‐2012. Drillhole locations were picked up by DGPS. Downhole surveys were carried out with a single‐shot camera in the RC holes to obtain the dip of the hole; azimuth was calculated from the set up of the hole. Aircore and Reverse Circulation drilling carried out to collect 1m riffle split or scoop samples, or 4m composite scoop samples which were then resampled on 1m intervals where anomalous gold values were returned. Samples were pulverised to produce a 40g charge for fire assay with AAS finish. Aircore drilling was used for the results quoted at the Matisse prospect and Reverse Circulation drilling used for all other areas. Aircore drilling was carried out by Goldfire Drilling, and RC drilling carried out mainly by Ausdrill, with 3 of the holes quoted drillholes (WARC035, 037 and 039 drilled between the Forrest Belle and Boudie Rat pits) being drilled by K and J Drilling. No other details have been found regarding the drill bit sizes and other drilling information.
Drill lines are variably spaced, depending on the prospect area and how far advanced the prospect was. Drill spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource estimates.
LATITUDE CONSOLIDATED LIMITED ACN 080 939 136 Ground Floor, 16 Ord Street, West Perth WA 6005 (t) 08 9482 0550 (w) www.latitudeconsolidated.com.au
Samples were analysed by KalAssay Laboratories in Kalgoorlie except for the samples from drill holes WAAC002 (KalAssay Perth) and WARC030 (KalAssay Leonora). The analytical method used was a 40g Fire Assay with AAS finish for gold only, which is considered to be appropriate for both the material and the mineralisation.
The Mineral Resource estimate was divided into 11 block models for the purpose of grade estimation. The Au domain wireframes were constructed in MicroMine by Wild Acre Metals Ltd (the previous owner of the property). Micromine software was used for all processes, including drill hole database, geological interpretation, wireframing, block model construction, grade interpolation, Mineral Resource classification and reporting of the Mineral Resource estimate. The interpretation of the mineralisation domains was carried out at a nominal 0.5 g/t cut off. Sections normal to the trend of the mineralisation were generated and outlines interpreted. The individual outlines were connected with tie lines and wireframe solids of the individual mineralised zones were produced with a total of 15 solids produced. The solids contain up to 4 metres of internal dilution (downhole) so as to establish shapes which allow continuity between sections. Solids were validated using Micromine validation tools. Depth extent was carefully considered and the volumes did not extend down dip beyond a limit considered reasonable by the Competent Person. A weathering surface representing top of fresh rock was modelled based upon drill logs of weathering event, and built into the block models. The weathering domains were used to assign density values. A total of 1,012 RC holes (48,240 m) and 30 DD holes (3,189 m) support the Mineral Resource estimate.
These figures include 57 RC holes (6,397 m) drilled by Wild Acre to verify historical drill hole locations and tenor of mineralisation. 225 aircore holes support the geological interpretation. Quality assurance and quality control (QA/QC) programs were used for the Wild Acre drilling, with certified standards, laboratory standards, field duplicates, laboratory duplicates, repeats, blanks and grind size analysis monitored. QA/QC results from the historical drilling are currently being sought, however the recent drilling has verified the historical sample grades, such that the Competent Person was satisfied they could be used to support the Mineral Resource estimate. Drill samples were flagged by the mineralisation and weathering domains they are located in. Drill samples were statistically analysed by geological domains and top cuts were applied where necessary. A top cut of 20 g/t was applied to all the drill samples constrained within the mineralisation envelopes prior to grade interpolation. This top cut was determined by statistical analyses of the sample assays.
11 block models with parent cell sizes 2 m x 5 m x 2.5 m (Easting, Northing, RL) were constructed for each deposit, compared to typical drill spacing ranging from 10 m (E) x 10 m (Y) to 40 m (E) x 12.5 m (Y) within the Measured and Indicated volumes. The block sizes were chosen to best fit the Measured volume drill spacing. Subcelling was used to ensure the wireframe domains were adequately filled with blocks. Grade was interpolated using inverse distance to the power of 3 (ID3). A variety of search ellipse orientations were used for the grade interpolation parallel to the strike and dip of the mineralisation all with a standard search radius. Grade interpolation was run within the individual mineralisation domains acting as hard boundaries. A density of 2.0 t/m[3] was assumed for the oxide and a density of 2.6 t/m[3] assumed for the fresh material.
These are considered reasonable by the Competent Person, for the host rock units and style of mineralisation. The block models were depleted in volume according to the mining voids present. The block models were validated by comparing the block model grades with adjacent drill hole grades, in cross section. Records of historical and recent mining were compared against the Mineral Resource estimate, however the mining records lacked detail to allow for a meaningful reconciliation. No deleterious by products were modelled.

A reporting cut‐off grade of 1.0 g/t Au was used to report the Mineral Resource, and is considered a reasonable value for an open pit Au deposit in the Eastern Goldfields, close to infrastructure. The geological domains extend to a maximum depth of 150 m below surface.
The geological interpretations allowed for up to 4 m of downhole dilution. No other mining assumptions were made. The Competent Person believes the Mineral Resource as reported has a reasonable chance of eventual economic extraction due to its proximity to infrastructure (near Leonora, W.A.).
No metallurgical studies have been completed at this stage. It is intended to undertake a full metallurgical study when further resource work is undertaken and a decision to mine is made.

A weathering surface representing top of fresh rock was modelled based upon drill logs of weathering event, and built into the block models. The weathering domains were used to assign density values. A total of 1,012 RC holes (48,240 m) and 30 DD holes (3,189 m) |

| holes (6,397 m) drilled by Wild Acre to verify historical drill hole | ||

| estimate. | ||
| Drill samples were flagged by the mineralisation and weathering | ||
| domains they are located in. | ||
| Drill samples were statistically analysed by geological domains and | ||
| topcuts were applied where necessary. A topcut of 20g/t was |

| statistical analyses of the sample assays. | ||
| 11 block models with parent cell sizes 2 m x 5 m x 2.5 m (Easting, | ||

| drill spacing ranging from 10 m (E) x 10 m (Y) to 40 m (E) x 12.5 m | ||

| blocks. | ||
| Grade was interpolated using inverse distance to the power of 3 | ||
| (ID3). A variety of search ellipse orientations were used for the grade | ||
