Middle Island hits 100m at 2.02 g/t gold at Sandstone

Middle Island Resources’ Two Mile Hill gold deposit near Sandstone has shown its class with a whopping 100m intersection averaging 2.02 grams per tonne gold from a large-diameter core hole drilled to collect samples for ore sorting trials.

The new intercept, from a downhole depth of just 55 metres, included 7m at 18.1 g/t gold and is well in excess of the 1.1 to 1.4 g/t grade in Middle Island’s exploration target for its 100%-owned Two Mile Hill tonalite deeps deposit.

The large diameter diamond core hole was drilled to a depth of 284.5 metres in a relatively poorly drilled section of the deposit.

The primary objective of the hole was to collect new material for definitive trials of some innovative ore sorting technology that may result in a significant increase in grades through the mill, courtesy of a relatively inexpensive separation of waste ore from mineralised ore in the proposed underground mine section.

Shallow oxide material will also be tested to determine whether ore sorting could also improve returns from a proposed open pit above 140 metres.

Initial testwork excited the market in January by showing it could deliver an increase in head grade of between 185% and 257%. Middle Island’s 600,000 tonne-per-annum Sandstone mill is located just 4kms south of the deposit.

Managing Director, Rick Yeates, said: “Ore sorting offers the potential to make a significant positive impact on the economics of the Two Mile Hill tonalite deeps deposit. Should the new, more definitive ore sorting campaign replicate or improve on the initial trial results, bulk underground mining at Two Mile Hill becomes a very real opportunity that would substantially extend and enhance the envisaged production schedule.”

Middle Island is already planning the next phase of drilling on the assumption that the ore sorting trials by Steinert in Perth, using technologies such as X-ray and laser scanning, will confirm the positive early results.

The next stage of drilling will encompass 12 holes with RC pre-collars and diamond tails to drill out of the upper half of the tonalite deeps target from a depth of 140 metres to about 420 metres. The drill out will be on a nominal 40m x 40 grid, allowing the exploration target to be potentially upgraded to a mineral resource.

The drill program is also designed to generate the maximum number of intercepts through the banded iron formations intruded by the Two Mile Hill tonalite plug, targeting high grade gold mineralisation associated with pyrite replacement.

Drilling is planned to commence in about three weeks once the ore sorting trials have been fully evaluated and is expected to take about eight weeks to complete.

With funding in place after a December placement that raised almost $2 million, Middle Island will now set a cracking pace as the ASX junior races towards its objective of gold production.

Great. Being a part of this project will excite members. Hopefully, this material has a thick oxidation profile to introduce some low cost of mining and processing. At this stage, hole and sample integrity should not be downplayed. QAQC should be make the hallmark. Anyone that jokes with it needs a cool sanction to keep him alert since the future looks indicated and measured. This deposit should see exploitation. Trucks must be on site as soon as possible as far as mining timing is concern.
