Superior Mining initiated exploration work on the Redcastle property by retaining a field geologist with over 40 years of experience who has worked for many exploration and mining companies to complete geological mapping of the the project area (see Interpretive Geology map).

A soil sampling program was subsequently carried out over the project area in December 2012. Assays were returned, plotted and contoured (see Redcastle Soil Gold Geochemistry map). The last 2 km2 in area to the north was not sampled during the soil sampling program because of a layer of transported overburden masking the area. This part of the property was subsequently subjected to a Phase 1 shallow drilling program.  A deeper and extended Phase 2 drilling program followed after the Australian Ministry of Mines & Petroleum granted an approval to the Company to carry out the Phase 2 drilling program.

Soil Geochemistry

The soil geochemistry sampling has indicated the background threshold is 2 ppb. There are several anomalous results above this threshold:

•     The most significant result received is 102 ppb gold supported by 11 ppb some 280 m to southeast. These two values straddle a NW-trending porphyry dyke up to 100 m wide and 500 m long. Porphyries in the area are well known to contain gold mineralization.

•     There are two lower order gold anomalies. The first is an 11 ppb gold anomaly located in the southeastern corner of the tenement (claim) block. This is supported by a 5 ppb gold anomaly 200 m to the east. The second is a 13 ppb gold anomaly that lies near a SSW-trending quart vein that perhaps trends towards an abandoned shaft some 600m to the SSW.

•     Other weak anomalies, ranging from 5 to 8 ppb, are scattered through the southern half of the tenement block. Many are associated with metal detector scrapings for alluvial gold.

A follow-up soil geochemistry sampling was carried out on a 25 m by 25 m grid pattern over the 110 ppb gold anomaly. Additional soil geochemistry was completed on a 50 m by 50 m grid pattern over the lower order anomalies. These follow‑up sampling programs were undertaken concurrently with the first drilling program on the section of the property to the north overlain with a layer of transported overburden masking the area.

In total, 119 infill soil samples were collected around the gold anomalies highlighted in the December 2012 soil geochemistry program.  The infill sampling confirmed the 102 ppb gold anomaly over porphyry from the December 2012 soil sampling program with sample RP399 assaying 208 ppb. See the full listing of soil sampling results.

Phase 1 Drilling

The Company embarked on the phase 1 drilling program to penetrate through the cover in the northern part of the property immediately after it had received the approval of the Department of Mines and Petroleum (the regulatory body). The Company contracted Topdrill of Kalgoorlie, West Australia to engage their Rotary Air Blast (RAB) drill rig to complete 52 holes drilled for 826 m, each averaging 16.5 m.

Drilling commenced on February 20, 2013 and was completed by February 24th. The transported overburden ranged up to 15 m thick. Hardpan was encountered in most of the drill holes, between about 0.5 m and 3 m.

A 3 kg sample was collected every four metres from the transported overburden and then a 3 kg sample was collected one metre into the rock interface. See Phase 1 Drilling map.

Samples were then transported to Intertek Minerals Group (formerly Genalysis Laboratories, who have served the Australian mineral industry for over 30 years) in Kalgoorlie for sample preparation. Once the preparation was completed, Intertek then transported the prepared samples to the Perth laboratory for analysis.

All samples were analyzed for gold. Samples in the rock interface were also subjected to additional analyses, which included arsenic, antimony, bismuth, tungsten, copper, lead, zinc and nickel. Duplicates and standards were inserted every 20th sample interval. The most significant values returned are:

Phase 2 Drilling

A phase 2 drilling program was carried out in early May 2014, involving a total of around 1,400 m of drilling in slightly more than 50 holes. 

Drilling was designed to drill through the cover, which varied from several meters thick to somewhat over 50 m, to test the bedrock interface. That is, drilling was carried out through the young, non-mineralised cover to the old Archean bedrock.

A least 500 samples are being analysed, with the results expected in June.
