CS PROJECT - UPDATE
Sunrise Resources plc (ticker symbol 'SRES'), the AIM-traded
diversified mineral exploration and development company ("the
Company"), is pleased to provide this positive update on testwork
and details of a new development in the potential commercialisation
of the CS Project.
HIGHLIGHTS:
-- Variability testing of samples from across the deposit
indicate consistent results as a high quality natural pozzolan.
-- Pozzolan testwork accelerated. Samples now submitted to
accredited laboratory for certification testing. Results expected
within 45 days.
-- Testing also identified a potentially valuable opportunity
for production of Perlite, a product in high demand in the
construction and other industries (refer below for more
details).
-- Concept Study in progress to evaluate commercial options for
development of the project will be expanded to include perlite
production.
Commenting today, Executive Chairman Patrick Cheetham said: "I
am delighted at the rapid progress made by Magmatics Inc. in
testing of the CS Deposit for the production of natural pozzolan
and that we can move so quickly to certification testing. The
uniform performance of samples from across the surface of the
deposit is very encouraging. The discovery that this same material
may also have commercial application as perlite is an unexpected
and exciting development that could add substantially to the
opportunities to commercialise this project."

Detailed Information
The Company's Pozz Project, which includes the CS Deposit, was
established to search for and acquire, at low-cost, deposits having
potential for the production of natural pozzolan. Natural pozzolans
are seeing increased use in cements and concrete as a "greenhouse
gas friendly" alternative to Portland cement.
Further details on the Company's opportunity in natural pozzolan
can be found on the Company's website at:
http://www.sunriseresourcesplc.com/projects/pozz-overview
The staking of the CS Deposit in Nevada was announced on 14
November 2016 and the Company moved quickly to carry out initial
testwork. The results of this initial testwork, announced on 22
December 2016, were very positive for the production of natural
pozzolan and justified a concept study and testwork programme to
evaluate the economic viability of the project, announced on 25
January 2017.
Pozzolan Testing
The first stage in the work programme, variability testing, is
well advanced at Magmatics' laboratory in Idaho. The objective of
the variability testing is to define the areas of the deposit at
surface having the best pozzolanic properties. In each test, the
reactivity of the pozzolan/Portland cement/sand/water mix is
assessed by testing its strength against an index mix of Portland
cement/sand/water mix after curing for 7 days and then again after
28 days curing (curing involves chemical reaction and
hardening).
The initial "strength against index" results of variability
testing at 7 days are now available and show a very favourable low
variability across the deposit, with results in line with those
previously reported from selected samples.
It was originally planned that variability testing would be
followed by a programme of grind size optimisation to maximize
pozzolanic reactivity prior to certification of the pozzolan. The
results obtained to date indicate that we have already achieved a
workable grind size and that we can bypass this time-consuming
testing stage. Consequently, samples have now been submitted to CTL
Thompson, Inc. in Denver, a leading accredited cement and
construction industry materials testing laboratory, for
certification of CS pozzolan according to ASTM C618N(1) . This will
be important in establishing the material's credentials to future
customers.
Perlite Testing
Perlite is a glassy raw material which, when heated in a
furnace, pops like popcorn and expands by up to 20 times in volume
into a white or pale coloured, low density material used in:
-- Various industrial and household applications such as
insulation, paint texturing, plaster and concrete fillers, building
materials fillers, formed insulation, field conditioners (soil
porosity enhancement), and fire proofing.
-- Filter aids (in competition with diatomite).
-- Insulating industrial cryogenic storage vessels.
-- As a potting medium in gardening and horticulture to aid
water retention and aeration of the soil.
Following simple torch heating tests which suggested the CS
Deposit samples expanded significantly on heating, two samples were
submitted to the perlite testing laboratory at the New Mexico
Bureau of Geology and Mineral Resources(2) alongside a commercial
sample of perlite considered to be one of the highest quality
perlites in North America (Socorro reference sample). The results
are tabulated below:

The CS samples yielded a high brightness, low density expanded
product. Expanded apparent densities of commercial perlites vary in
the range 2-11 lbs/ft(3) .
With just two samples tested so far, more work needs to be done,
but initial indications are that the samples tested represent
commercial quality perlite. Sample 2 outperformed the high quality
reference material on some parameters and gave close and very
acceptable results on other parameters. The very low expanded
density of Sample 1 may have advantages in certain applications,
for example in insulation.
The application of perlite to different industrial uses is
dependent not only on these properties but also on the size
distribution of the expanded particles. The expanded test products
have been subject to a full sieve analysis and results indicate
potential in a wide range of commercial applications. However, at
this stage the expansion tests have been carried out on a specific
size fractions (for both the CS samples and the reference material)
and further testwork is necessary to determine which applications
can be targeted in commercial practice.
The CS Deposit can now be described as both a perlite and a high
quality pozzolan.
The Concept Study for development of the CS Deposit will now be
expanded to consider production of perlite alongside pozzolan and
define options for commercialisation of project.

According to the United States Geological Survey, in 2014, the
last year for which it has published data, the total value of
expanded perlite used in the USA was 454,000 tons having a value of
US$151,000,000, an average of US$332/ton.
Notes:
1. ASTM International is a globally recognized leader in the
development and delivery of voluntary consensus standards. ASTM
C618N is the standard for natural pozzolan.
2. The New Mexico Bureau of Geology and Mineral Resources
provides perlite analyses for industry, government, and the public
through the perlite laboratory, an applied-research and
public-service facility. The perlite laboratory is the only readily
accessible perlite testing facility in the United States.
3. Whilst the Company has established that its CS mining claims
contain significant outcrop areas and exposed vertical thicknesses
of glassy rhyolite meeting the chemical requirements for natural
pozzolan, the Company has not yet carried out any drilling and no
code-compliant Exploration Target or Mineral Resource or Ore
Reserve has been defined.
