Gold nugget weighing 13oz recovered from the Bullet Hill prospect.
Significant nugget finds identify further bedrock targets at the Sandstone gold project, WA
- Aggregate initial tribute gold production of 148.6oz in nuggets for the months of July and August 2017, of which Middle Island’s share is 22.2oz gold.
- Production includes individual nuggets up to 13oz in weight.
- Tribute activities have identified a further three potential bedrock gold targets at the Bullet Hill, Three Mile and McClaren prospects within the Sandstone gold project.
- The McClaren prospect is of particular interest, with in-situ ironstone hosting an abundance of coarse platy, free gold that appears to be of primary origin.

Aircore drilling identifies new gold targets at Davis Prospect, Sandstone gold project (WA)
- Results from geochemical auger and aircore drilling at the Dais prospect (comprising Davis East and Davis West) have defined several significant new blind gold anomalies beneath a blanket of transported sheetwash cover.
- Four cohesive anomalies, with peak values up to 688ppb Au (0.68g/t) have been defined over individual strike lengths of ~200m, some of which may prove to be linked over strike lengths of up to 600m.
- Each of the anomalies are consistent with those defining nearby, high grade open pit deposits that have been mined and processed.
- All new gold anomalies at Davis lie within 1km of the Company’s 600,000tpa Sandstone gold processing plant, consistent with an area hosting the highest density of gold deposits within the entire Sandstone greenstone belt.
- Davis is the first of the ‘weights of evidence’ (WoE) targets to be tested by geochemical drilling, providing considerable confidence that other WoE targets may generate similar anomalies.
- Along with the current resource definition drilling at the nearby Wirraminna deposit, each of the Davis targets provide further potential to contribute to an early mill recommissioning decision.
- Reconnaissance RC drill traverses will be immediately undertaken over two of the Davis anomalies in order to understand the nature and tenor of associated saprolitic mineralisation.

Second expansion for Sandstone with option to acquire nearby Dandaraga gold project
Highlights
- Middle Island has signed an Option Deed to acquire a 100% interest in the Dandaraga gold project, exercisable at any time within a three-year period upon payment of $200,000.
- Dandaraga is situated 16km southeast of Middle Island’s Sandstone gold project and processing plant, and 4km south of the haul road from the Lord Henry and Lord Nelson deposits.
- The Dandaraga geology comprises a succession of banded iron formations (BIFs), ultramafics, gabbros and, importantly, dolerites.
- The Dandaraga project incorporates a series of historic gold workings that remain untested or poorly tested by modern gold exploration.
- The more significant Agnes workings are developed on a zone of stockwork quartz veining within a dolerite unit, adjacent to which free gold has been identified in a highly brecciated, gossanous and quartz-veined BIF.
- The Dandaraga project is largely well-exposed, facilitating rapid, conventional and cost-effective exploration for additional targets.
- The Dandaraga acquisition presents both an immediate and attractive open pit exploration target at the Agnes gold prospect, and consolidates considerable exploration acreage into Middle Island’s well-endowed Sandstone gold tenure.
- The transaction is entirely consistent with Middle Island’s strategy to extend and enhance the proposed production schedule for the Company’s 100%-owned Sandstone gold processing plant.
- It will be the second such expansion, following the Company’s June signing of an option to acquire the Wirraminna gold project, situated immediately adjacent to the Sandstone project and within 1km of the processing plant.

Exceptional gold recoveries from new tests on Two Mile Hill tonalite deeps deposit, Sandstone gold project (WA)
- Positive metallurgical testwork results indicate gold recoveries of 93% to 97% for the Two Mile Hill tonalite deeps mineralisation at the Sandstone gold project.
- >58% of gold is recoverable via gravity concentration prior to leaching.
- Leach testwork exhibits rapid leach kinetics, with 90% of total gold extraction achieved within the first two hours on run-of-mine (ROM) composite samples following gravity gold recovery.
- Bond ball mill work index of 16.4kWh/t confirms ore amenability for treatment through the Sandstone mill.
- Low reagent consumptions and no deleterious elements indicate no issues for future treatment.
- Diamond drilling underway to extend Two Mile Hill tonalite deeps mineralisation from 500m depth to at least 850m depth.
415.2m at 1.34g/t Au intersected in Two Mile Hill diamond drilling at Sandstone gold project, WA
Diamond Drilling Results Announcement - 7 June 2017
Diamond Drilling Results Announcement - 7 June 2017
- Gold intersection of 415.2m at 1.34g/t Au, ending in mineralisation, encountered in deepest diamond hole, MSDD156, drilled to date at the Two Mile Hill prospect within Middle Island’s Sandstone gold project.
- Cored portion of MSDD156 mineralised from start to finish and remains open at depth, with the final interval comprising 66.9m at 3.27g/t Au (from 432m to end of hole at 498.9m).
- When combined with the RC pre-collar (MSDD155) immediately adjacent to MSDD156, the extended mineralised intercept becomes 457.9m at 1.28g/t Au.
- Veining, alteration and associated gold mineralisation in MSDD156 is consistently developed throughout the entire hole.
- The intercept in MSDD156 is entirely consistent with previous diamond drilling at Two Mile Hill, which includes:-
372.7m at 1.52g/t Au
230.4m at 1.62g/t Au
353.3m at 1.04g/t Au
141.0m at 2.30g/t Au
156.3m at 1.14g/t Au
230.4m at 1.62g/t Au
353.3m at 1.04g/t Au
141.0m at 2.30g/t Au
156.3m at 1.14g/t Au
- Drilling confirms the presence of a substantial and ubiquitously mineralised system measuring 250m in strike and up to 80m in width that is mineralised to at least 500m depth.
- Result increases the possibility of bulk underground mining beneath the proposed open-pit cutback at Two Mile Hill.
Drilling represents part of three-hole programme supported by WA Government drill funding.

RC drilling results from McIntyre & Two Mile Hill prospects at Sandstone gold project, WA
- New 29-hole RC drilling results on two prospects - McIntyre and Two Mile Hill - within Sandstone gold project in WA enhance gold inventory potential.
- Results confirm broad intervals of very shallow dipping gold mineralisation at McIntyre.
- Persistence of a broad mineralised zone at McIntyre suggests more significant grades may be encountered down dip from initial lower grades.
- McIntyre to be further drilled along strike and down dip in 2H 2017.
- New Two Mile Hill results to be incorporated into an updated resource estimate for this deposit as part of ongoing pit re-optimisation.
- Sandstone continues to build after >400m gold mineralised intersection from diamond hole at Two Mile Hill and acquisition of adjoining >10,000oz gold resource at Wirraminna, announced this week.
- Better RC drilling results from both the Two Mile Hill and McIntyre prospects include:-
2m at 44.7g/t Au
5m at 7.59 g/t Au
25m at 0.81g/t Au
4m at 3.37g/t Au
5m at 7.59 g/t Au
25m at 0.81g/t Au
4m at 3.37g/t Au
McIntyre & Two Mile Hill RC Drilling
Gold developer, Middle Island Resources Limited (Middle Island, MDI or the Company) is pleased to announce that all gold assay results have now been returned for reverse circulation percussion (RC) drilling completed during the June quarter at the Two Mile Hill and McIntyre prospects within the Company’s Sandstone gold project in WA.
The purpose of the RC drilling programme was twofold:-
- Infill previous RC drilling in the northeast quadrant of the Two Mile Hill open pit deposit in order to clarify the mineralised continuity in an area critical to pit optimisation.
- Infill previous rotary air blast (RAB) and RC drilling at the McIntyre prospect to confirm and extend the presence of thick, shallow zones of gold mineralisation.
