Paterson North

Sipa’s Paterson North Project in the North West of Western Australia is an exciting new exploration discovery for the Company in one of the most highly endowed yet under-explored mineral provinces in Australia. Sipa is earning up to an 80 % interest in the project with Ming Gold.

  • Large Copper >0.1% and Gold up to 1.3g/t plus Molybdenum Silver and Tungsten identified.
  • Sipa’s Project immediately adjoins Antipa Minerals’ Citadel Project to the south containing the Magnum and Calibre copper gold deposits (>1Moz gold and >100,000t Cu) , where Rio Tinto Exploration is spending up to $60M to earn a 75% interest.
  • Located 120km north of the world-class Telfer gold and copper deposits and the OCallaghans Tungsten Deposit.
  • Collaborative research study with CSIRO building geological model and interpreting mineralisation history and style.

During 2017 Sipa has conducted further extensive Aircore and RC drilling and ground geophysics. This has resulted in the delineation of a strong zone of alteration within the broader 4km long copper anomaly which has copper greater than 0.1% and anomalous gold up to 1.3g/t Au, Molybdenum up to 323ppm and Tungsten up to 0.33% (Figure 3). A recent gradient array IP survey correlates directly with this zone as shown in Figure 4 and represents a compelling drill target.

CSIRO Collaborative Study

The collaborative research study with CSIRO uses the (TIMA) Tescan Integrated Mineral Analyser (SEM) Scanning Electron Microscope as its key breakthrough technology, coupled with integrated geological interpretation of in house and publically available bedrock geology and geophysics by a team led by John Miller and Adam Bath of CSIRO.

An initial pilot study using chip tray samples from Ming Gold’s drilling has been completed and already shows that mineral species such as the titanium group of minerals can been quantitatively identified and texturally analyzed to determine areas of stronger alteration related to mineralisation. The data also allows some quantitative genetic conclusions to be made regarding actual mineral chemistry and para-genesis of mineralisation. Due to the large number and spatial distribution of the samples it will enable 3d dimensional mapping of a range of important geochemical indicators, which should provide clear vectors to potentially economic mineralisation.

Figure 5 below shows the resultant scans from a meter of drill chips analyzed through the scanner and shows the distribution of minerals in the sample.

Project History

Ming Gold Pty Ltd has conducted a program of exploration between 2011 and 2015 over E45/3599 including reprocessing aeromagnetic data, regional and follow up detailed ground gravity collection and in 2015 the EIS (Western Australian Government Exploration Incentive Scheme) co-funded initial air core drilling campaign.

Ming's drilling program was designed to test targeted areas of Proterozoic basement based on the geophysical data and analysis. Data collected included geochemical analysis, magnetic susceptibility, regional geological information, as well as to evaluate the depth-to-basement from surface information. 

A total of 31 aircore-reverse circulation holes were drilled across the tenement targeting principally the coincident gravity-magnetic anomalies. 163 samples of the Permian-Proterozoic contact and Proterozoic basement were collected from the 3,205m drilled.

Sipa's maiden reconnaissance program was completed in mid-September 2016 and comprised ~4,500m of Aircore/RC drilling in 45 holes. The objective was to test the Obelisk prospect, within the Great Sandy Tenement and, at a minimum, replicate the anomalous values encountered in previous drilling by Ming Gold Limited.

The drilling confirmed that the anomaly is continuously developed over the entire strike length, including a 1.5km long zone where strongly anomalous copper and gold results were returned.
