Hot Chili Commences Scoping Study on Productora Copper Project, Chile• Leading engineering and project development group AUSENCO
appointed to undertake study• Two drill rigs scheduled to re-commence drilling activities next week as part of a 70,000m drilling programme
• Extensional drilling results from Productora are currently being compiled and are expected to be announced shortly
Hot Chili Limited (ASX Code: HCH) is pleased to announce that it has formally commenced a Scoping Study on the Company's flagship Productora copper-gold-molybdenum project in Chile. Following an extensive tendering process, the Company has appointed leading engineering and project development group AUSENCO to undertake the study. In addition, Hot Chili has assembled an experienced development study management team to assist Ausenco and ensure development study timeframes are achieved. The Scoping Study is scheduled to be completed in the third quarter of 2012. Following a successful AU$22.3 million capital raising in December 2011, the Company will be fully funded to undertake an aggressive activity budget in 2012.Development studies are being undertaken in parallel with an extensive 70,000m drilling programme aimed at significantly expanding the size of the first resource at Productora. Assay results from 10 weeks of Reverse Circulation (RC) and Diamond (DD) drilling completed at Productora prior to Christmas are being compiled and are due to be announced shortly. Two dedicated multi-purpose RC/DD drilling rigs are due to recommence drilling next week.
Productora Copper-Gold-Molybdenum Project
The Productora project is Hot Chili's flagship project in
Chile. The project is located 15km south of the township of
Vallenar, at low altitude (less than 1,000m) in Chile's 3rd
region. Since drilling commenced in August 2010, the Company
has outlined a large-scale, bulk tonnage
copper-gold-molybdenum project amenable to open pit mining.
In September 2011, the Company defined its first resource
from within the central 1.4km extent of the project,
reporting a JORC compliant resource of 85.1Mt grading 0.6%
copper,
0.1g/t gold and 146ppm molybdenum (0.8% copper equivalent)
for 483,000 tonnes of copper, 290,000 ounces of gold, 12,418
tonnes of molybdenum (644,000 tonnes of copper
equivalent).
Significant exploration has outlined a 9.5km deposit
footprint at Productora where extensional drilling by Hot
Chili and previous explorer Teck has already confirmed
significant drilling intersections over 3.7km strike extent.
The Company has commenced a major second-phase drilling
programme to achieve rapid resource growth and is planning to
fast-track a decision to mine by late December 2013.
Preliminary economic benchmarking has indicated robust
economics for a potential future open-pit operation ideally
located to existing infrastructure including the PanAmerican
Highway, rail, power and port (40km distance) as shown on
Figure 1.
The Company is aiming to establish a significant resource
base at Productora from an identified 280 - 320M tonne target
mineralisation at similar grade to that estimated in the
first resource announced from the centre of the project.
Assay results from a significant extensional RC drilling
programme along the northern extents of the Productora
deposit footprint are currently being compiled and are
expected to be released shortly. The Productora target
mineralisation is summarised in Table 1 below.

References to exploration target size and target mineralisation in this announcement are conceptual in nature and should not be
construed as indicating the existence of a JORC Code compliant mineral resource. Target mineralisation is based on projections of established grade ranges over appropriate widths and strike lengths having regard for geological considerations including mineralisation style, specific gravity and expected mineralisation continuity as determined by qualified geological assessment. There is insufficient information to establish whether further exploration will result in the determination of a mineral resource within the meaning of the JORC Code
About AUSENCO
Ausenco sets high global standards for leading engineering
and project management services in the resources and energy
sectors. Across 32 offices in 20 countries, Ausenco's people
seek innovative solutions for their clients in the Energy,
Environment & Sustainability, Minerals & Metals, Process
Infrastructure and Program Management sectors. The Company's
process engineering and project capabilities are
internationally recognised with extensive experience gained
in copper, gold, uranium, nickel and iron ore. Ausenco
services all stages of the project lifecycle, from pit to
port, and has completed studies and
Engineering-Procurement-Construction-Management (EPCM)
contracts around the world.
Ausenco's Minerals & Metals team, based in Santiago and
Brisbane, was chosen for the Scoping Study because of its
expertise and experience with large scale minerals projects,
and proven experience with copper project development from
scoping study to project implementation. Ausenco has
successfully designed and constructed the Lumwana
concentrator (55 ktpd) in Zambia, the Phu Kham concentrator
(33 ktpd) in Laos and is currently executing the GDP3
expansion (new 50 ktpd concentrator) of the Gibraltar Mine
for Taseko in Canada and the Constancia Project for HudBay in
Peru.

* Copper Equivalent Calculation
Copper Equivalent (also Cu Eq*) Calculation represents the total metal value for each metal, multiplied by the conversion factor, summed and expressed in equivalent copper percentage. These results are exploration results only and no allowance is made for recovery losses that may occur should mining eventually result. However it is the Company's opinion that elements considered here have a reasonable potential to be recovered as evidenced in similar multi-commodity natured mines elsewhere in the world. Copper equivalent conversion factors and long-term price assumptions used follow:
Copper Equivalent Formula= Cu % + Mo(ppm)x0.0008 + Au(ppm)x0.6832
Price Assumptions- Cu (US$1.80/lb), Mo (US$15/lb), Au (US$850/oz)
