FINAL STRONG COPPER ASSAYS FROM DRILLING PROGRAM CONFIRM POTENTIAL FOR 100% OWNED TOLLU PROJECTRedstone Resources Limited (ASX: RDS) ("Redstone" or "the Company") is pleased to announce the last of the outstanding copper intercepts from the Company's recently completed drilling program and also from further analysis of historical samples from previous drill programs at its 100% owned Tollu Project ("the Project"), which has achieved a number of the planned key objectives.
KEY OUTCOMESConfirmation
of shallow
oxide/transitional copper miner lisation potentially amenable to
evaluation of a low cost development path as part of the broader development strategy of the
larger and higher grade sul
hide prospects
Identification of the Forio prospect over 250m of mineralised strike which remains open in all directions
Confirmation of up dip co Prospects
tinuity of the sulphide mineralisation at Chatsworth and Eastern Reef
Identification of copper mineralisation in re‐assay of historic pr
spects Kilruddery and Hertsecombe
Subsequent to the Company's 11 January 2016 and 22 February 2016 announcements, further results from
the most recently completed drilling program
have now been received. These
results, which include
copper grades of up to 4.02%, are consistent with work previously conducted on the Project area. These results were primarily from the Chatsworth, Main Reef and Eastern Reef Prospects.
Significant copper intercepts from the recent assaying of samples from both the most recent and historical drill programs, primarily from the Chatsworth, Eastern Reef and Forio Prospects include: Chatsworth Prospect31m at 1.18% Cu from 20m including 6m at 2.98% Cu from 25m (TLC090)
4m at 1.22% Cu from 13m (TLC091)
12m at 1.45% Cu from 178m including 4m at 2.16% Cu from 18
7m at 1.05% Cu from 6m (TLC090)
1m at 1.33% Cu from 96m (TLC020)

Commenting on the continued excellent results, Redstone's Chairman, Richard Homsany stated:
"These additional strong results continue to increase confidence in the
Tollu Project. Drilling
activities have focussed on the known prospects with the exception of Forio. The Project's potential
copper endowment is not
onstrained. The board has enhanced confidence that additional drilling
can lead to further ore grade copper discoveries, both oxide and sulphide.
The
success of the shallow drilling at the previously undri led prospects, especially at Forio,
highlights the underlying potential for the identification of further mineralisation in other narrow veins for near surface copper mineralisation. With only limited drilling, the Forio Prospect shows significantly longer strike length than both the Chatsworth and Eastern Reef Prospects.
The mineralisation at Forio is very significant in that it is located in a dilational zone to the north west of the Tollu Fault, wh ch is in a different location to the previously discovered mineralisation. Its current strike length, which remains open to the south, is y t to be effectively drilled out below
50m. Recent
results demonstrate some of the
widest and strongest
copper mineralisation
discovered at these levels at the Project to date.
These results allow the Company to commence preliminary investigation of the economic viability of the high grade near surface copper mineralisation at Tollu. Such an operation, if studies prove it
to be viable,
may present short term development options generating early cash flow with
significantly lower up front capital expenditure."
Summarised below are key further results for the Chatsworth, Main Reef, Eastern Reef and Forio Prospects. Table 1 annexed to this release contains all drilling results to date.
Tollu Project (Redstone 100%)Redstone's 100% owned Tollu Project is located in the southeast port on of the West Musgrave region of Western Australia. The Project is approximately 20km south east of the Blackstone Community on the Company's 100% owned tenement E69/2450 (Figure 1). The Company has identified 16 prospects within the Tollu Project (Figure 2).
The Project consists of a large swarm of hydrothermal copper rich quartz veins in a mineralised system covering an area at least 5km2. Malachite rich gossans associated with quartz veins are exposed at the surface and form part of a dilatational system between two major structures within the Tollu Fault Zone.

The main activity concentrated on the known higher‐grade zones at the Chatsworth, Main
Reef and Eastern Reef Prospects within the Tollu Project. mineralised system.
The primary purpose was to validate the Tollu
Aim of Recent Assaying of Previous Drill SamplesDrill campaigns prior to 2015 concentrated on the known higher‐grade zones at the Chatsworth, Main Reef and Eastern Reef Prospects within the Tollu Project. The primary purpose of assaying the historical drill samples was to utilise all available data for geological understanding and potential contribution to the Tollu mineralised system.
FURTHER ASSAY RESULTS Chatsworth ProspectThe Chatsworth Prospect is a singl
sub vertical hydrothermal body exposed at the surface. This Prospect
forms part of the dilation system between two north south trending shears. The Chatsworth Prospect has been the main focus of much of the technical and drilling activity to date. Whilst the prospect appears to have been delineated along strike in the most recent round of drilling there still remains potential to infill the main mineralised zone above current deeper intersections and the ultimate depth continuity remains open (Figure 3). Further recent results are included in Table 1 below.
