Perth, Western Australia: 21 February 2018: Pioneer Resources Limited (the "Company" or “Pioneer”) (ASX: PIO), is pleased to provide the results from 2 diamond core holes drilled within the Company’s 100%-owned Sinclair Zone Caesium Deposit, located within the Pioneer Dome Project approximately 140km south of Kalgoorlie, Western Australia.
The Company is working towards open pit mining operations to extract the Sinclair Zone Caesium Deposit this year and while doing so, studies have identified that the mono-mineralic potassium feldspar “microcline” dominates the overburden within the proposed Sinclair Zone Caesium Deposit pit.
The final pre-mining drill-out at the Sinclair Zone Caesium Deposit is nearing completion (refer December Quarter 2017 Activities Report released 31 January 2018). 14 diamond core holes have been drilled targeting pollucite and overlying microcline, as well as 4 geotechnical holes drilled adjacent to the proposed pit walls (refer Figure 2).
It is noteworthy that microcline has been recorded in over 30 drill holes along the full length of the Sinclair Zone pit, so is well constrained spatially, however the 2 drill holes recorded here-in and the 14 pre-mining drill-out holes are the first to be analysed using the low-iron sample preparation technique.

NEW NICKEL SULPHIDE DISCOVERY AT GOLDEN RIDGE
22 metres at 1.02% Ni and 475ppm Cu at Leo’s Dam Nickel Prospect
Perth, Western Australia, 25 January 2018:
Pioneer Resources Limited ("Pioneer" or the "Company" (ASX: PIO)) is pleased to announce it has intersected significant nickel sulphide mineralisation in recently completed drilling at its 100%-owned Golden Ridge Project in the Eastern Goldfields of Western Australia.
The Company advises that drilling at the Leo’s Dam Prospect within the Golden Ridge project area has returned a highly significant nickel sulphide intersection of 22m at 1.02% Ni and 475ppm Cu from 202m. Results of the Company’s cobalt-focused drilling at the Project were released to the ASX on 24 January 2018.
The results of this phase of drilling validate and strengthen Pioneer’s geological model for the Golden Ridge Project, and it will now make plans for the next phase of field work at the Project as a priority.
The Discovery of a Broad Zone of Disseminated Nickel Sulphides at Leo’s Dam Validates the Blair Dome Structural Model and Enhances the Projects Prospectivity.
In an announcement to ASX dated 20 July 2015 the Company outlined an advance in the geological model for the Golden Ridge Project, including the proposition that an ultramafic dome (Figures 3a and 3b) is the dominant geological structure for the Project.
This is analogous to other major nickel sulphide mining camps located to the south of the Blair Nickel Mine (within the Golden Ridge Project), such as Kambalda and Widgiemooltha.
An additional hole drilled at the Leo’s Dam Prospect has provided further validation to this model, through the intersection of significant of nickeliferous sulphides.
• GRRC38: 22m at 1.02% Ni and 475ppm Cu from 202m
Including: • 3m at 1.27% Ni and 526 ppm Cu from 202m
• 4m at 1.23% Ni and 503 ppm Cu from 213m
• 4m at 1.08% Ni and 616 ppm Cu from 220m
Samples have been submitted for additional analysis and petrographic description, and results will be conveyed to the market when received.
Notes on GRRC38 from Pioneer’s Consultant Geochemist
. • Disseminated Ni sulphides are associated with two host rocks:
o Peridotite: best intersection 3m at 0.82% Ni and 157 ppm Cu from 170m o Pyroxenite: best intersection 22m at 1.02% Ni and 473ppm Cu from 202m.
• The sulphides are probably hydrothermally remobilised in origin
. • The sulphides are considered very high tenor: Peridotite nickel tenor of ~53%; Pyroxenite ~32%

Reverse Circulation Drilling Returns Strong Cobalt Mineralisation
The December 2017 drilling programme of 31 reverse circulation drill holes totalled 3,084 metres and focused on four cobalt targets: Rocket, Leo’s Dam, Anomaly 13 and Anomaly 14 Prospects.
All prospects are located within granted mining leases and an exploration licence along the eastern flank of the Blair Dome, a geological structure within the Golden Ridge Project. 16 holes intersected significant cobalt mineralisation (see Table 1 below).
This drilling programme is a consequence of a detailed review of the Golden Ridge drilling database specifically looking for cobalt mineralisation (refer to ASX Release dated 13 April 2017). The database holds records for holes drilled between 1975 and 2008 by other explorers and 2008 to the present by Pioneer, predominantly for nickel sulphide mineralisation indicators. Many samples were assayed for a range of elements, including cobalt, in addition to nickel.
