East Kemptville
Tin-Indium Project
As at June 11, 2015
TSX & NYSE MKT: AVL
Property Location
Project Description
The 100% owned East Kemptville Tin-Indium Project is located
approximately 55 km northeast of Yarmouth, Nova Scotia, Canada.
The property consists of 4 exploration licences and a Special
Licence covering over 10,000 acres in aggregate. East Kemptville
operated from 1985-1992 and was North America’s only large
primary tin producer before closing in 1992 due to a collapse in tin
prices after the international cartel was disbanded. Increasing
global demand for tin and limited tin supplies have resulted in
strengthening tin prices, creating an opportunity to consider redeveloping the tin-indium resource at East Kemptville. There is
excellent infrastructure in the area, including paved highway
access and grid power.
Mineral tenure at the East Kemptville mine site is held under a
Special License which was recently renewed for a three year term
expiring in February 2018. The Special Licence requires
exploration and development expenditures of $5.25 million over 3
years and is subject to receiving permission from the surface rights
holder to access the site. In May 2014, Avalon entered into an
agreement with the surface rights holder to secure access for an
initial drilling program, in 2014 and the agreement was recently
extended to allow for a second drilling program to be completed in
the summer of 2015. A 43-101 resource estimate of the historical
mine resource was subsequently reported in October 2014. In early
2015, Hains Engineering Company Limited completed a
Conceptual Redevelopment Study (“CRS”) to determine if there
was a business case for re-developing the site and to justify further
investment in feasibility study work. The CRS demonstrated
potential for positive economics based on recent metal price
forecasts and a development model similar to the historical 10,000
tonnes per day operation.
Project Next Steps
Avalon plans to proceed with an initial $1.2 million work program
to begin gathering the information needed to complete a
Feasibility Study in 2017. The work will include:
 a Phase 2 drilling program in the summer of 2015 with the
objective of bringing more Inferred Mineral Resources into the
Indicated category and drilling for extensions of the known
resources as well as testing two other exploration targets

Tin Markets
Rising tin prices over the past 10 years reflect growing global demand for tin due
to its increased application in electronics, where it is used in solders as a nontoxic alternative to lead. Production of tin concentrates from traditional sources in
southeast Asia has declined in recent years, increasing the need for new primary
supply sources such as East Kemptville to emerge.
Currently, most
analysts covering the
tin sector (including
the World Bank) are
forecasting increasing
tin prices over the next
ten years potentially
reaching US$25,000/
tonne by 2025.
However, short term
price volatility typical
for small market
commodities, has
been a characteristic
of the tin market for
the past 10 years and
is expected to continue.
New Applications for Tin

 bench scale metallurgical testing, using sample material
collected during the 2014 and 2015 programs, to verify
metallurgical recoveries, concentrate grades and evaluate ore
variability
 preliminary environmental studies to examine the nature of
the waste rock generated in any proposed mine, and to
identify and fill key data gaps with respect to permitting, water
management and treatment, and waste management
 completing a formal Preliminary Economic Assessment of the
Project
 securing surface tenure to the site

Strategic Advantages
 Infrastructure in place: accessible by paved highway and grid power on site
 Deep water port within 60 kilometres
 Skilled labour available locally: Yarmouth and other communities commuting
distance
 Politically-stable, mining-friendly jurisdiction (Government is supportive of
new investment in mineral development)
 Could achieve production by 2018
Mineral Resources
Following the completion of the seven-hole confirmation drilling program in
2014, Avalon released an initial 43-101 resource estimate containing an
estimated Indicated Mineral Resource of 18.47 million tonnes averaging
0.176% tin, 0.173% zinc and 0.064% copper and an estimated Inferred
Mineral Resource of 16.95 million tonnes averaging 0.148% tin, 0.122% zinc
and 0.062% copper at a 0.10% tin cut-off grade. At the 0.10% tin historical cut
-off grade the resources roughly approximate what was calculated to have
been left unmined by the original operator following closure of the mine in
1992. This cut-off grade will be adjusted in future resource estimates to reflect
present metal prices and cost assumptions.
Cautionary Statement
The Conceptual Economic Study is preliminary in nature and includes inferred mineral resources
that are considered too speculative geologically to have the economic considerations applied to
them that would enable them to be categorized as mineral reserves. There is no certainty that the
preliminary economics indicated in the Study will be realized. The results were released in Avalon’s
News Release of February 25th, 2015.
Mineral Resources Estimate
(October 31, 2014)
Conceptual Redevelopment Study
The purpose of the CRS was to confirm the business case
for the re-development East Kemptville before securing the
necessary approvals to proceed with physical work at the
site. The proposed development model assumes a
conventional open pit mining and processing operation at a
production rate of 10,000 tonnes per day similar to the
historical operation. Hains recommends that a new
operation take advantage of recent innovation in
metallurgical recovery technology for tin ores that can
improve recoveries for tin as well as by-product copper and
zinc. In addition, Hains recommends building a tin refinery
at the site that will produce tin ingots as a final saleable tin
product. This strategy offers the potential for creating valueadded in Nova Scotia, reducing the business risks
associated with using third party processors and potentially
enhancing the overall economics of the operation.
Sustainability
Reporting
In December 2014, Avalon
released its third Sustainability
Report which includes a selfassessment of sustainability
performance in accordance with
the Global Reporting Initiative
G4 core level and the Mining
Association of Canada’s
Towards Sustainable Mining
standards. It can be
downloaded from Avalon’s website.
1. CIM definitions were followed for Mineral Resources.
2. The Independent Qualified Person for this Mineral Resource estimate is Donald Hains, P. Geo.
3. The resource estimate is based on 275 drill holes totalling 29,587 metres drilled between 1979 and 1991 by previous operators and 7
holes totalling 984 metres drilled by Avalon in 2014.
4. Drill data was organised in Maxwell DataShed and for estimation purposes was transferred to MineSight 3D software, wherein the block
model was developed.
5. Resources were estimated by interpolating composites within a block model of 5x5x3 m blocks. Interpolation used the inverse distance
squared method with localization of higher grades.
6. Indicated material was defined as blocks with an average distance to interpolated composites of ≤ 50 m while inferred material was
defined as blocks with an average distance to interpolated composites of ≤ 75 m, thus limiting the depth of the resource to 75 m below
drill holes.
7. Three metre composites were capped at 1% Sn, 1% Zn, and 0.5% Cu which are the 99th percentiles of assay data for those elements,
reducing contained tin by about 1% compared to uncapped resource.
8. The median density of available data of 2.78 t/m3 was used for all mineralized material.
9. Several possible cut-off grades are reported in this resource estimate. Based on past mining practice at East Kemptville a cut-off grade
of 0.1% Sn is reasonable. However, no value or cost estimates are available at this time.
10.Mineral resources do not have demonstrated economic viability and their value may be materially affected by environmental, permitting,
legal, title, socio-political, marketing, or other issues.
The technical information contained in this document has been reviewed and approved by Bill Mercer, Ph.D., P.Geo. (ON), P.Geo. (NWT),
Vice President Exploration of Avalon, the qualified person for the purposes of National Instrument 43-101.
