Gold Road - High Grade Gold Intersected at Santana Prospect

Gold Road Resources (ASX:GOL) has identified gold mineralisation in at least four prospects at the Sun River-Wanderrie Camp Scale Target on its North Yamarna tenements in Western Australia following a programme of targeted bedrock drilling. The programme focused on the Supergroup Anomaly, a high priority target over six kilometres long, and returned a best intercept of 1.97 metres at 6.50 g/t from 181 metres at the Santana Prospect.


Highlights

  • Bedrock gold mineralisation identified in at least four prospects tested over a five kilometre strike of the Supergroup Anomaly
  • Diamond hole 16TADD0002 intersects 1.97 metres at 6.50 g/t Au from 181 metres at the Santana Prospect

Gold Road Resources Limited (Gold Road or the Company) is pleased to announce that an initial programme of targeted bedrock drilling at the Sun River-Wanderrie Camp Scale Target, located within the Company’s 100%-owned North Yamarna tenements in Western Australia, has identified gold mineralisation in at least four prospects.

The drilling programme focused on the Supergroup Anomaly, a high priority target over six kilometres long, with the best intercept returned from diamond hole 16TADD0002 drilled at the Santana Prospect - 1.97 metres at 6.50 g/t Au from 181 metres within a broader zone of gold anomalism of 21.35 metres at 0.75 g/t Au from 180 metres (Figures 1 and 2).

A second diamond hole, 16WDDD0002, testing aircore anomalism at the Vai Prospect, intersected 1.0 metre at 2.16 g/t Au from 128 metres in a shear zone, almost 700 metres east of the main Supergroup trend (Figure 2).

In total, the drilling programme comprised six widely spaced diamond holes and 13 reverse circulation (RC) holes specifically targeting bedrock gold mineralisation associated with discrete aircore gold anomalies (prospects) forming the six kilometre long Supergroup Anomaly (Figure 2).

The diamond drilling also provided important initial information relating to the primary structure and stratigraphy of the Supergroup Anomaly geology. Gold mineralisation in excess of 0.5 g/t was identified in 11 of the 19 holes drilled, which is a very successful first pass test. Follow-up drilling is now being planned to test the dip and strike extensions of intersected mineralisation, and will initially focus on the Santana, Blackmore and Vai Prospects.

Gold Road Executive Director Justin Osborne said “To intersect gold mineralisation in 11 of the first 19 holes drilled into the Supergroup Prospects is considered a significant success. This first pass drilling programme covered a large area with very few holes, and confirmed bedrock gold mineralisation, including high-grades, in almost all Prospects. We remain very excited about the potential of this trend and we will follow up with further drilling to discover the ore bodies we believe to be there.”

Drilling intersection details

The intersection in 16TADD0002 is located on the middle of three drill sections designed to test the length of anomalism of the Santana Prospect, which is the highest priority prospect within the Supergroup Anomaly Drilling specifically targeted the stratigraphy beneath a broad zone of low-grade gold anomalism hosted in a leached saprolite profile defined through aircore drilling in 2015. Primary gold mineralisation intersected in 16TADD0002 is hosted within a zone of silica-biotite-chlorite-pyrrhotite-arsenopyrite bearing sheared volcaniclastics, situated to the east of the mafic sequence that typically hosts gold mineralisation in the main Supergroup Anomaly. This shear is interpreted to represent an adjacent structure to the main Supergroup trend. The mineralisation is similar in style and host lithology to the Attila South Deposit approximately 10 kilometres to the north, which is host to a 220,000 ounce gold resource.

Diamond hole 16WDDD0002, testing the Vai Prospect, intersected 1.0 metre at 2.16 g/t Au from 128 metres. The 16WDDD0002 intersection is hosted within a mineralised trend that is located approximately 700 metres to the east of the main Supergroup Anomaly mineralisation trend and represents a completely separate and parallel mineralised structure (Figure 2). On the same drill section RC drill hole 16WDRC0014 intersected 4 metres at 0.57 g/t Au from 45 metres in the up-dip projection of the 16WDDD0002 intersection. This drilling was following up an aircore anomaly of 4 metres at 0.63 g/t Au.

Holes 16TADD0002 and 16WDDD0002 were the highest grade intercepts in the 19-hole diamond and RC drill programme testing aircore anomalism at the Santana, Blackmore, Hendrix, Vai, and Satriani Prospects. The diamond drilling was designed to provide early stratigraphic and structural information, while the RC drilling specifically targeted the zones of highest aircore gold anomalism. While gold mineralisation intersected was generally low-grade the drilling has confirmed the continuity of bedrock mineralisation along a five kilometre length of the target area.

Other significant RC intersections include (Figure 2):

  • 1 metre at 1.79 g/t Au from 117 metres (16TARC0006)
  • 1 metre at 1.11 g/t Au from 61 metres (16TARC0008)
  • 1 metre at 1.01 g/t Au from 92 metres (16TARC0019)

Following interpretation and modelling further work will be planned to test the better bedrock gold intersection at the Santana, Satriani, Blackmore, and Vai Prospects.

Results are pending for an aircore drilling programme conducted along the previously untested five kilometre southern strike extension of the Supergroup Anomaly in April 2016 which comprised 108 holes. Samples have been submitted to the laboratory for analysis and should be available in the September 2016 quarter.
