QUARTERLY ACTIVITIES REPORT
FOR THE PERIOD ENDED 31 MARCH 2018
30 April 2018, Pioneer Resources Limited (“Pioneer” or the “Company” (ASX: PIO)) is pleased to update the market with a summary of activities undertaken during the March Quarter of 2018.
PIONEER DOME Caesium Potassium Lithium Project – Eastern Goldfields, WA
MAVIS LAKE and RALEIGH Lithium Projects – NW Ontario, Canada
GOLDEN RIDGE COBALT AND NICKEL PROJECT – Eastern Goldfields, WA
INFILL DRILLING CONFIRMS CONTINUITY OF HIGH-GRADES AT THE SINCLAIR ZONE CAESIUM DEPOSIT PREPARATIONS FOR MINING ADVANCE
Perth Western Australia, 19 April 2018: Pioneer Resources Limited ("Company" or "Pioneer", ASX: PIO) is pleased to provide a drilling update for its 100%-held Pioneer Dome Project in the Eastern Goldfields of Western Australia, which includes the Sinclair Zone Caesium Deposit.
A programme of diamond-drilling was principally undertaken to infill 5 sections with the strongest caesium mineralisation (in the form of the mineral pollucite) in preparation for final open pit mine design work. Each of the key sections returned pollucite intersections in line with earlier modelling.
Caesium (Pollucite) intersections included:
and 7.18m at 16.04 Cs2O from 47.88m
Lithium mineralisation (petalite and lepidolite), which occurs peripheral to the caesium mineralisation, included:
PRE-MINE DRILLING AT THE SINCLAIR ZONE CAESIUM DEPOSIT.
The programme totalled 20 drill holes and produced 1,333.29m of core. Of these, 15 holes targeted caesium or lithium mineralisation, 4 holes were completed adjacent to the proposed pit walls to provide geotechnical information, and 1 hole became blocked and was abandoned. Most holes also intersected potassium (microcline).
With lithium and caesium results to hand, Pioneer’s geological consultants from the Mitchell River Group are revising the Mineral Resource Estimate for caesium.
Potassium (microcline) samples, which require specialised processing, are currently being analysed, with results expected before the end of April.
The open pit design and confirmation economic study are on track to be concluded by the end of May, 2018.

ASSAYS CONFIRM MULTIPLE, WIDESPODUMENE-PEGMATITE INTERSECTIONS MAVIS LAKE LITHIUM PROJECT, ONTARIO, CANADA
Perth, Western Australia: 6 April 2018: Pioneer Resources Limited (the "Company" or “Pioneer”) (ASX: PIO), in conjunction with its joint venture partner International Lithium Corp. (“ILC”) (TSX Venture: ILC.V), (together the “Joint Venture”) is pleased to provide the results of a highly successful drilling programme at the Mavis Lake Lithium Project in the province of Ontario, Canada, (Refer ASX announcement 19 February 2018).
STANDOUT INTERSECTION* | MF18-53: 55.25m at 1.04% Li2O from 82.75m
Other intersections* of spodumene-bearing pegmatites returned:
DRILLING AT MAVIS LAKE LITHIUM PROJECT
The programme, targeting the Fairservice Pegmatite 6 Prospect, (see Figures 1 and 2 below) consisted of nine diamond core holes for a total of 1,591 metres.
All nine holes intersected significant spodumene mineralisation, usually in the form of multiple wide zones of pegmatite.These results greatly enhance the prospectivity of the Project.
Image 1:MF18-53. The entire interval, including internal waste, returned 55.25m at 1.04%Li2O from82.75m. Higher grade zonesincluded 25mat 1.12%Li2O from82.70m and13.70m at1.41% Li2Ofrom 122.30m
