LARGE 1000m x 250m AU MMI SOIL ANOMALY DEFINED AT YIDBY GOLD PROJECT

3 New Gold Targets generated & untested by Historical Drilling

  • MMI Soil Geochemical results have been finalised and returned from SGS laboratories in Perth comprising a total of 520 samples with a peak value of 29.1 ppb Au
  • Structural interpretation using 1VD Aeromagnetic data extended to include the new geochemical targets
  • MMI Au in soil anomalism coincident with cross faulting of the interpreted sheared BIF/Ultramafic contact
  • T1-T3 exploration targets set the basis for a new Program of Works (POW) submission to the DMP

Surefire Resources NL (ASX: SRN, "the Company" or "SRN") is pleased to announce the results of its soil geochemical survey that was undertaken in an area southeast and along strike from the Yidby Gold Deposit (refer to 27th July and 30th August ASX Announcements). 520 samples were collected over a 100m x 25m grid and analysed at SGS Perth using the mobile metal ion (MMI) protocol – an advanced geochemical technique used in finding undercover mineral deposits (Figure 1).

The geochemical results were plotted on a heat map which has led to the definition of three discrete and significant soil anomalies for addition to the company's exploration portfolio (Figure 1). The newly defined 'Money Anomaly' is a large NW trending 1000m x 250m area of MMI Au in soil anomalism (T1). The peak value of 29.1 ppb Au (YS0304) within T1 is approximately 58 times the background reading of ~0.5 ppb Au (Table 1). Two other smaller geochemical targets were also defined lying adjacent to T1 and are approximately 200m x 100m wide (T2-T3). A POW submission is now being designed to test these targets in future exploration drill programs at the Yidby Gold Project.

Figure 1 Plan view of the newly defined MMI Soil Anomalism along strike from the Yidby Gold Deposit. The green historical drill collars that are located to the East are 700 m away from the centre of the peak soil anomalism of T1 and were ineffective at testing gold mineralisation. Drillholes in this SE area were historically drilled to explore for BIF hosted magnetite not gold mineralisation.

The T1-T3 targets have never been drill tested by previous explorers and provide potential for new gold discoveries to be made directly across the road and along strike from the Yidby Gold Deposit (Figure 2).

Surefire Managing Director Vladimir Nikolaenko commented:

"We are very excited to define such a large Au geochemical anomaly directly along strike and across the road from the Yidby Gold Deposit."

"We can now add these additional exploration targets to the portfolio and drill test these alongside development of the Yidby Ore body"

About Yidby Gold Project

The Yidby Gold Project is situated within the southern portion of the Yalgoo-Singleton Greenstone Belt near Ninghan Station Homestead. To the south of the project is the Extension Hill iron ore mine, Mount Gibson Gold Mine. The three exploration licences cover 113.77km² with three gold prospects hosting significant gold mineralisation. Historic workings occur at Ninghan Mining Centre, Delaney Well, and Cashens Find, while historic drilling which reported significant gold intercepts has occurred at Yidby Road, Delaney Well, and Cashens Find Prospects.

The project is centred in a highly attractive location being within 1km of the Great Northern Highway, a major arterial road which services the various mining centres, and is the state's main link to the north west. The project is 400km along this route from Perth.

The project is also surrounded by several significant gold projects. The Mount Gibson Gold Project is 30km to the south, the Rothsay Gold Project is 30km to the west. 65km to the north-east along the Singleton-Yalgoo Greenstone Belt is the +1.1 million-ounce Minjar Gold Project, while the millionounce Kirkalocka Gold Project is approximately 70km to the north-east. 40km along the Great Northern Highway is the Paynes Find Mining Centre.
