Gold Road Resources (ASX: GOR) has defined new gold anomalies at two prospects within the South Yamarna Joint Venture project after completing regional aircore drilling programmes. The latest drilling confirmed gold anomalism at Yaffler South, with best intersections of 4 metres at 1.24g/t Au from 46 metres, and Kingston North, best intersections 2 metres at 1.29g/t Au from 56 metres.
- Strong gold anomalism intersected in regional aircore drilling at two prospects within the South Yamarna Joint Venture, including:
- 22 metres at 0.38 g/t Au from 44 metres at Yaffler South, including 4 metres at 1.24 g/t Au from 46 metres (16SYAC0865)
- 4 metres at 0.74 g/t Au from 54 metres at Kingston North, including 2 metres at 1.29 g/t Au from 56 metres (16SYAC0974)
- RC drilling at Hirono confirms bedrock gold mineralisation
Gold Road Resources Limited (Gold Road or the Company) is pleased to announce the completion of regional aircore drilling programmes testing the Yaffler South, Riviera and Kingston North targets, located in the Riviera‐Smokebush Camp Scale Target area, and a Reverse Circulation (RC) drilling programme at the Hirono target on the South Yamarna Joint Venture (SYJV) tenements, a 50:50 joint venture with Sumitomo Metal Mining Oceania Pty Ltd (Sumitomo).
The infill aircore programme of 193 holes (Figures 1 and 5) targeted anomalism identified by earlier aircore drilling completed at the Yaffler South, Riviera and Kingston North targets (ASX announcement dated 20 September 2016). The new drilling successfully confirmed gold anomalism at Yaffler South and Kingston North with best intersections of 4 metres at 1.24 g/t Au from 46 metres at Yaffler South and 2 metres at 1.29 g/t Au from 56 metres at Kingston North. Follow up programmes are in preparation with further work planned for the first half of 2017.
At programme of RC drilling (15 holes) at Hirono Prospect (previously YAM10) returned a broad low‐grade porphyry hosted intersection of 17 metres at 0.40 g/t Au from 142 metres below a previous aircore result of 19 metres at 1.06 g/t Au from 62 metres, with another six holes also intersecting low grade mineralisation. Detailed geological interpretation of the anomalism is in progress to determine the next stage of activity for this Prospect.
Gold Road Executive Director ‐ Exploration & Growth Justin Osborne said: “The results received from the final programmes completed in 2016 confirmed a number of new gold anomalies in the South Yamarna JV project, adding to our portfolio of prospective drill ready targets. Planning for our 2017 exploration programme is complete and activities are expected to commence within the next few weeks, with a total budget approved with our Joint Venture partner Sumitomo of up to $4 million for the year. We consider the geological prospectivity of the South Yamarna tenements to be some of the most exciting in the Yilgarn and are looking forward to renewed focus on the project this coming year”.
Yaffler South Aircore Programme
Infill aircore drilling at Yaffler South improved the definition of the gold anomalism over a 1.8 kilometre strike length. New results included an intercept of 22 metres at 0.38 g/t Au from 44 metres including 4 metres at 1.24 g/t Au from 46 metres (16SYAC0865) at the contact of a dolerite and felsic tuff unit (Figure 2). The gold anomaly has coincident arsenic‐molybdenum anomalism, and is situated proximal to a major regional shear zone, suggesting a splay structure is the likely host to the gold mineralisation. Structural interpretation is ongoing to allow targeted follow‐up drilling as a next phase.
Kingston North Aircore Programme
Infill aircore drilling at Kingston North targeting an interpreted set of north‐west striking shear zones returned a best intersection of 4 metres at 0.74 g/t Au from 54 metres, including 2 metres at 1.29 g/t Au from 56 metres (16SYAC0974) in sheared intermediate sediments. This intersection remains untested to the east (Figure 3). Weathered sulphides, often associated with shear hosted gold mineralisation, were noted during logging. A second zone of anomalism approximately three kilometres east of the Toppin Hill Prospect was extended to over 2.5 kilometres in strike (Figure 1) by a new intercept of 4 metres at 0.44 g/t Au from 35 metres, including 1 metre at 1.39 g/t Au from 38 metres (16SYAC0890).
Riviera Aircore Programme
Results from infill aircore drilling at Riviera returned one hole with a gold grade greater than 100 ppb, 3 metres at 0.28 g/t Au from 2 metres (16SYAC0812) associated with Cainozoic sand. Riviera is three kilometres north and along strike of the Smokebush Prospect and remains prospective. This target has been lowered in the priority list, with geological interpretation being finalised.
Hirono RC Programme
Follow up RC drilling at the Hirono Prospect intercepted relatively thick, low‐grade mineralisation hosted in felsic porphyry, interpreted to be similar to the Gruyere Porphyry. A best intercept of 55 metres at 0.23 g/t Au from 142 metres (Table 5), including 17 metres at 0.40 g/t Au from 142 metres (16SYRC0091), associated with quartzsulphide veining within the porphyry suggests potential exists for a reasonable sized mineralising system. Final structural and geological interpretation is ongoing to target possible zones of higher grade or width within the Prospect area (Figure 4).
Follow‐up RC drilling to test for bedrock gold mineralisation at Yaffler South and Kingston North are in preparation and further work is planned for the first half of 2017. Requirements for additional work at Riviera and Hirono will be assessed on completion of the ongoing geological interpretation.
