Since completing its 2018 field season, a number of developments have contributed to a significantly improved understanding of the geological significance and context of Sipa’s Obelisk discovery and its surrounding tenement package.
Most notable has been the recent confirmation of a significant
Important information that has come from Rio’s announcement that can be applied to Sipa’s exploration activities include:
•A similar polymetallic copper, gold, silver, molybdenum, bismuth and tungsten signature at both Winu and Obelisk. Peak assay values from Sipa’s drilling are 22g/t Au, 2% Cu, 16g/t Ag, 323ppm Mo, 0.3% Bi and 0.3% W (see ASX Releases, 19 June 2017 and 12 Oct 2017);
•The mineralisation discovered at both Winu and Obelisk is associated with quartz sulphide veins with dominant sulphides, chalcopyrite, pyrite and pyrrhotite.
Airborne EM was a key factor in the identification of the anomaly that Rio first drilled in late 2017, resulting in the Winu discovery.
Sipa has now contracted Skytem to conduct an airborne EM survey in May 2019 following the completion of further EM surveying for Rio Tinto. Field logistics to support the survey have commenced.
In addition, further
Concurrently with the Airborne EM a
Ionic leach assaying is a relatively new and very sensitive assaying technique which is able to detect very low elemental responses in soils.
The technique is being widely trialed in the exploration industry with reported success in detecting anomalous metallic element signals through transported cover.
Following an initial orientation
Results show anomalism in a number of elements, including copper, which appear to be correlated with drilled bedrock mineralisation at both Obelisk and Andromeda, around 20km
At Obelisk, a
Importantly, the soil copper anomaly is largely untested by drilling and, where partially tested by recent aircore drilling, corresponded to bedrock copper mineralisation in drill holes PNA090 and PNA091 (refer to ASX announcement of 14 September 2018). This is a priority drilling target for the 2019 field season.

The drilling at both south Obelisk and Aranea will be supported by a WA Government
This is a competitive program and, importantly, Sipa was awarded the only such grant for this round for any projects in the Paterson Province. The grants have been an important part of Sipa’s exploration strategy as the area was, up until a few years ago, almost unexplored with drilling.
An important part of the Company’s reconnaissance exploration approach is to understand fundamental geology, mineralising processes and prospectivity.
The North Paterson Province is now one of the most active and prospective new exploration frontiers in Australia, with exploration programs underway by major mining companies such as Rio Tinto, FMG, and Newcrest, as well as a number of junior exploration companies including Sipa, Antipa Minerals and Encounter Resources (under agreement with IGO).
This high level of activity, combined with Rio Tinto’s Winu copper and gold discovery 10km west of Sipa’s tenements, highlight its

The program included the following activities for the quarter:
•Regional mapping and rock chip sampling: A program of regional mapping and rock chip sampling commenced in
Areas of focus included the Goma, Lawiyadul, Katunguru, Awodi Padwat and Lugwa Jopudung prospects (Figure 3).
•Soil sampling: Assessment of Sipa’s extensive >70,000 pXRF soils database indicates that a number of anomalies remain open. On the basis of this data, additional tenements have been acquired with soil sampling underway over these areas and other tenements were rationalised.
•Diamond Drilling: Diamond drilling of a further two holes for 713.4m was completed during the quarter at Akelikongo.

Logging is ongoing with assay results for these two holes and the holes drilled in late 2018 expected in the coming weeks.
During the quarter, Sipa secured a new highly prospective
