Maggie Hays Lake Joint Venture Project
Introduction
Click to enlarge
The Maggie Hays Lake project is located 140km SE of Southern Cross. The project is immediately southeast and along strike from the Maggie Hays and Emily Ann nickel sulphide deposits.
Latest Development by Pioneer
The project is subject to a joint venture with LionOre Australia (Nickel) Limited, who are managing the exploration.
Project Summary
Geological Setting
The Lake Johnston greenstone belt trends NNW, is 70km long and up to 20km wide. An assemblage of greenschist-facies ultramafic, mafic, felsic volcaniclastic rocks and banded ironstones occupy the core of the belt and are flanked by more homogeneous, fine to coarse grain mafic rocks.
The belt is surrounded and locally intruded by regional granites and cut by a number of ENE trending Proterozoic dykes, the largest of which is the layered Jimberlana Dyke. The ultramafic unit does not crop out within the target area.
Exploration Activity
The project is considered prospective for both Nickel Sulphide and gold mineralisation. At the Maggie Hays Lake prospect, RAB drilling of a magnetic unit within the northern-most part of the tenement has confirmed ultramafic rocks, often pervasively talc altered and in part carbonated; and with intercalated sediments. While the nickel geochemistry clearly maps ultramafics, several holes are anomalous in copper and PGM, confirming the nickel sulphide prospectivity of this project.

MLTEM and FLTEM surveys have identified a possible deep bedrock conductor anomaly which is considered a priority nickel sulphide target.
Auger sampling completed by previous explorers partly covered Pioneer's current tenement. Results show a relationship between anomalous gold values and linear structures highlighted by aeromagnetic imagery. Pioneer is also aware that a number of nuggets have been recovered from the lake within or adjacent to Pioneer's tenement.
