With the successful completion of an initial aircore drilling program late in January, the Australian gold explorer Middle Island Resources Limited (ASX:MDI) is commencing a substantial ~12,800m, multi-rig, reverse circulation (RC) drilling campaign this week at its flagship Sandstone gold project in central WA.
The Companyâs RC drilling campaign is targeted to validate, expand and/or test around 14 open pit gold targets within 4km range of its wholly-owned Sandstone gold processing plant. The open pit gold targets and deposit extensions designated for drilling have been prioritised by the Company following a detailed internal and external technical review.
Initial Aircore Drilling Program Completed at Sandstone
Middle Island initiated a major, multi-phase open pit drilling campaign at its Sandstone gold project in January 2020 to target around 17 identified prospects and deposits within the projectâs tenure. The campaign comprises an initial aircore program, followed by two phases of RC drilling and a limited program of oxide diamond coring.
The Company has completed the initial aircore drilling program, covering 200 holes (1,806m) in January end, prior to RC drilling. The aircore work included 20m x 20m drilling of two laterite occurrences, in addition to 80m x 80m palaeo-surface geochemical drilling to ascertain the limits of earlier defined gold anomalies and maiden palaeo-surface drilling of one new target.
Though the initial aircore drilling program has been completed, the drilling results are pending and are expected to be returned in adequate time to refine scheduled RC drilling of the palaeo-surface gold geochemical targets.
The Company informed that the palaeo-surface aircore drilling is necessary to provide better anomaly definition before RC drilling, but will be considered later and is expected to deliver more significant results.
RC Drilling Program Commencing This Week
The Company is about to begin with the RC drilling program this week, which is designed to improve and/or upgrade existing open pit Mineral Resources before completing an updated pre-feasibility study in the June 2020 quarter and revisiting the Sandstone project recommissioning decision.
Both the aircore and RC drilling represent the first programs of the significant multi-phase drilling campaign, consisting of at least ~20,000m of drilling. The Company will report the progressive results of the drilling programs on a continuous basis.
Middle Island has also planned to undertake further RC and diamond drilling programs late in the March quarter if required. These programs are targeted:
To access significant additional exploration funding for this major exploration and resource definition drilling campaign, the Company also announced a fully underwritten Entitlement Issue, which will close on 12 February 2020.
With the AUD gold price close to record levels, Middle Island expects any additional Mineral Resources determined during the drilling campaign to considerably improve the outcome of the projectâs updated PFS (Pre-Feasibility Study). The Company expects the PFS update to result in an encouraging gold mill recommissioning decision.
As at 2:24 PM AEDT on 11th February 2020, MDI is trading at $0.004.
