Tritton Copper Mine (NSW)
PRODUCTION
Copper production for the March quarter continues to be strong at 8,073 tonnes, a
slight increase on the previous quarter and in line with the mining plan.
Ore processing performance remains consistent with 417,244dmt of ore being
processed during the quarter.
The processing plant was shut down for three days in March for a reline of the SAG Mill
and to complete yearly statutory electric infrastructure inspections.
Copper recovery at 95.18% was higher than the prior quarter and is due to higher
copper ore head grade processed during the quarter.
Improving reliability of the mine equipment fleet, through strategic equipment
replacement and improved maintenance practices, has continued to be a high focus.
During the quarter two new 63t underground trucks were added to the fleet, following
on from two delivered during the December quarter. A further four new trucks are on
order and scheduled for delivery in the coming months. A new drill rig was also
acquired during the quarter.

COSTS
C1 unit cash costs for the quarter were A$1.98/lb, a 17.5% improvement on the first two
quarters of FY16 and was as a result of our ongoing focus on cost reduction strategies,
lower product handling costs and lower TC/RC’s, reflecting the lower benchmark
TC/RC’s for the 2016 calendar year, which were finalised during the quarter.

Exploration and Project Development
EXPLORATION - TRITTON MINES AND SURROUNDING TENEMENTS
Aeris currently holds 184,600 hectares in the prospective Tritton VMS district. This is made
up of four granted exploration and three mining leases. Six major mafic complexes
have been identified within a sequence of sedimentary rocks with a combined strike
length of greater than 100km. Numerous anomalies have been identified and remain
untested in the Tritton region (see Figure 1).
An exploration strategy has been steadily evolving for the region and has been
extremely effective in both identifying and testing for VMS sulphide systems as
demonstrated by Aeris’ exploration success at Avoca Tank, Kurrajong, Carters and
Budgery.
The quality of the remaining targets in the Tritton region and the potential for further
discoveries in this large VMS copper district remains excellent. Aeris’ previous success
and the knowledge that Besshi VMS systems like Tritton are characterised by repeats
along strike, multiple horizons and lenses and significant depth potential gives the
company great confidence for the discovery of additional deposits along the multiple
prospective horizons within the Tritton region.
Tritton Deeps
At Tritton the current Ore Reserve extends down to the 4,165mRL level while the Mineral
Resource extends down to the 4,000mRL (1,280m below surface).
Importantly
mineralisation has not been closed off at depth below this level.
A drilling program has commenced to better define the orebody below 4,200mRL,
known as “Tritton Deeps”. The Tritton Deeps project is a multi-phase drill program
designed to test mineralisation continuity below current drilling information and extend
the Mineral Resource Inventory to the 3,800mRL level (1,480m below surface).
The initial Tritton Deeps Phase 1 drill program was completed in H2 CY2015 with the
results announced to the ASX on 2 October 2015 (correction announced 20 October
2015). The program, totaling 17 holes (6,641m) was designed to primarily confirm
continuity of copper mineralisation between the 4,200mRL to 4,000mRL levels (the
window approximately 200m below the 30 June 2014 Ore Reserve). Two drill holes were
extended deeper and intersected copper mineralisation down to the 3,830mRL level
(1,460m below surface) indicating copper mineralisation is not closed off a depth (see
Figure 2). Drill hole intersections above 4,050mRL are perpendicular to sub perpendicular
to mineralisation. Below 4,050mRL drill holes intersect the mineralisation at more acute
angles and the true width of the orebody is more difficult to determine. This is relevant
for drill holes TRNM009, TRNM010 and TRNM021a.
The second phase of the Tritton Deeps drilling program was completed in Q1 2016. The
program was designed to drill out the Tritton orebody to 40m x 40m drill spacing
between the 4,200mRL to 4,000mRL, and thereby increasing the level of geological and
grade certainty. Work is now being undertaken to update the Tritton Mineral Resource
and Ore Reserve estimates.

PROJECT DEVELOPMENT - MURRAWOMBIE UNDERGROUND MINE
On 21 March 2016 the Company announced that the Aeris Resources Limited Board
had approved the development of the Murrawombie Underground mine.
The deposit is located in the southern area of the Girilambone Complex close to the
current North East and Larsens mines and approximately 20 kilometres from the Tritton
Processing Plant (see Figure 1). The deposit is the largest known concentration of
copper metal on Aeris’ tenements outside the Tritton deposit and was previously mined
in the 1990s as an open pit to access the oxide portion of the orebody for heap leach
processing. However, the sulphide portion was not mined at that time due to its
unsuitability for heap leaching.
Mineralisation below the open pit is defined by multiple sulphide lodes bounded by
graphitic shear zones. The dominant copper mineral, chalcopyrite, is typically
associated with massive pyrite, with lesser disseminated pyrite. The massive sulphide
lodes are continuous over 200m in length and extend up to 400m down dip.
The deposit remains open at depth. Historical drilling has intersected copper
mineralisation 600m below surface (4,600mRL).

Quarterly Activities Report | For the period ended 31 March 2016
The Murrawombie Underground mine was originally developed in 2007, with a portal
and 600 metres of decline. The mine was then put into care and maintenance during
the Global Financial Crisis in 2008.
As at 30 June 2015 the Ore Reserve was 3.3 million tonnes at 1.3% copper.
The Murrawombie Underground mine is expected to have a mine life of 7 years
producing up to 650,000 tonnes of ore per annum (see Figure 3).
Capital expenditure to develop the initial Stage 1 lens, over a period of 18 months, is
projected to be $6.4 million for infrastructure and equipment and $8.5 million for capital
development.
Preliminary site works have commenced and will leverage off infrastructure that already
exists. First ore is expected to be delivered to the Tritton Processing Plant by the end of
the June 2016 quarter.

Investments increased as a result of share price increases.
During the quarter the sale of the Temora and Currumburrama Exploration projects to
Sandfire Resources NL (Sandfire) was completed. Consideration was $2.5 million, paid in
Sandfire shares. The Sandfire shares were subsequently sold on—market during the
quarter.
Corporate capital expenditure for the quarter was nil.
On 31st December 2015 the debt restructure approved by Aeris shareholders on 15
December 2015 was completed. This resulted in the Senior Debt with Standard
Chartered Bank being reduced by 55% to US$50 million and the establishment of a three
year US$25 million Working Capital Facility with Special Portfolio Opportunity V Limited
(PAG SPV). During the quarter US$4.5 million was drawn down on the PAG SPV Working
Capital Facility.
