Surefire Resources NL Announces Further Exceptional Gold Results from Yidby Gold Project
Surefire Resources NL announced that further exceptional results have been produced from the final assays received from the October-November 2020 RC drilling program at the Yidby Gold Project in the Mid-West of Western Australia. These results further support the thick and broadly mineralised intersections announced 30 November 2020, which included several high-grade gold intervals. The drilling program included 20 drill holes for 1,687 metres and was the Company's initial exploration program at the recently acquired Yidby Gold Project. Three Prospects were targeted with the drilling program, including Yidby Road and Cashens Find as well as Delaney Well, and significant intersections were produced from all three prospects. Each drill hole intersected anomalous gold mineralisation and significant intersections were produced from 10 of the 20 holes completed. These intersections are tabulated below. The further significant intersections produced from the Yidby Road Prospect, such as the 16m @ 1.51 g/t Au from 50m including 4m @ 4.18 g/t Au and including 1m @ 13.43 g/t Au in YBRC009, have confirmed the extensive, thick and high-grade, intersections announced on the 30 November 2020. There is a strong association between the gold mineralisation and the massive veining associated with the quartz-feldspar intrusive porphyry. The porphyry has likely introduced or acted as a brittle conduit for gold bearing mineralised fluid into the surrounding high magnesium basalts and talc-chlorite schistose ultramafic rocks. Historical drilling intercepted the mineralised porphyry, initially by Normandy Exploration Pty Ltd. in 1996-1998, and then by Monarch Gold Mining Company Ltd. in 2006, producing the previously reported historical results. No drilling has taken place at the Yidby gold Project in the last 14 years. The recent RC drill results show both broader zones of mineralisation with higher grade intersections than the historical drilling. Further, the mineralisation is open down dip of the shallow intersections and along the north-westerly strike, that is interpreted to be part of a regional corridor that may continue for up to 5km along strike within SRN's tenements. To the north-west of drill hole YBRC007, which intercepted 56m at 1.97 g/t Au from a shallow 44m depth (previous announcement), strike extensions are completely open, providing an excellent target for follow up drilling. To the south-east the strike also remains open. Drill holes YBRC011 and YBRC012 were drilled targeting this strike extent and all results now in it appears more likely that these holes came close to the mineralisation, intersecting the dispersion haloes within the clay saprolite zone. The shallow, albeit lower grade, saprolite anomaly was present in both drillholes, even though the strong veining encountered in nearby holes to the north was not. At the Cashens Find Prospect, situated just under 2km to the north of Yidby Road Prospect, three RC holes were drilled targeting the historic workings. The main part of the workings hosts gold mineralised veins and shears located adjacent to a felsic porphyry. The drilling beneath the main workings was successful in replicating historical drilling results and attained a significant 9m @ 4.17 g/t Au from 18m including 3m @ 9.41 g/t Au in CHRC001. Each of the three holes intersected upwards of 2 g/t Au within the westerly trending mineralised shear, that is interpreted to be part of a regional corridor that may continue for up to 5km along strike within SRN's tenements. Situated in the north of Exploration Licence application E57/2426, the Delaney Well Prospect encompasses a cluster of gold stopes, shafts, and costeans in the southern part of the Nyngan Gold Mining Centre. The Delaney Well Prospect was drilled by Capricorn Resources Ltd. (1989), Resource Exploration NL (1997), and WCP Resources Ltd. (2013). The north-south trending line of workings targeted in the initial program follow along quartz stockwork veining within biotite-tremolite-chloritic schists with gold occurring in steep plunging shoots. The initial program recorded the high grade intersect of 2m @ 17.7 g/t Au from RC drill-hole DRC-8. Significant gold intersections are tabulated below: The gold workings occur at the junction point between a north-westerly trending shear zone, and a north trending structure. The controls on the mineralisation remain to be better understood, and it appears that potentially steep plunging shoots have not been adequately tested by the shallow historic drilling. Lithologies drilled included fresh tholeiitic basalt with quartz veining. This area was targeted with five RC drill holes for a total of 312m. Results were significant and further work is required to follow up and repeat the historic high-grade intersections. 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 million- ounce Kirkalocka Gold Project is approximately 70km to the northeast. 40km along the Great Northern Highway is the Paynes Find Mining Centre. Preliminary interpretation of regional magnetic imagery has highlighted a series of northwest trending structures that correspond with both the Yidby Road and Cashens Finds prospects. The Yidby Road structure has truncated the axis of a major antiform, representing a structural high that is considered highly prospective for gold mineralisation. Both the Yidby Road and Cashens Find structures are interpreted to continue for over 5km within the Surefire Resources tenements and remain largely untested by drilling along strike of the prospect areas tested to date.
