Metals Demand Has Grown,
Sentiment Now Is Cautious
• Urbanization, industrialization continues in
China, SE Asia, India, parts of LatAm, MENA
driving industrial metals and energy demand
• Security & stability of supply are a concern in
China, Korea, Japan, Middle East, etc. and
select co.s e.g., fuel (coal, uranium), fertilizer
minerals, technology/critical metals, etc.
• Economic growth in China, EU, etc. is slower
• Metals prices and valuations are down
• Risk-off attitude is plaguing sector

Largest Mass Migration in History Sets
Theme for World‟s Rising Middle Class
• In the next 20 years, ~325 million people to move to urban areas in China
• China‟s middle class may to double to 600+ million by 2020
• A similar shift is occurring elsewhere around the world

Cautious Now; Long Term Demand Positive
• Mining companies have reduced spending
• Investors and lenders are very cautious
• Cash is king, may be primed for M&A
• Many „Juniors‟ are short of capital
• Tough markets may go into 2014
• Longer term - supply may struggle to meet demand
• Sporadic price spikes in metals markets can occur
• Constraining new supply are: Declining ore grades;
Higher costs; Fewer large deposits; Larger „takes‟
by Governments; Changing political winds; etc.

Cautious, Deliberate, Long Term View
Is Core to Cyclical Mining Business
• You can lose a fortune being optimistic about
the near term future – some have already
• As a legendary analyst said “Be careful
about looking to mountain tops as paths
through valley floors can be treacherous”
• Behre Dolbear focuses on geo-technical,
operating, business & financial issues that
impact exploration, development, operations
• We do not forecast metals prices
13. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
When To Call Independent Experts
• It is best to get Qualified expert advice early on
whether you are an owner, investor, etc.
• All too often experts are called when:
The company is out of money
Lenders are out of patience
Despair has set in
• Caveat Emptor – Buyer Beware
• Profitable projects are few
15. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Finding A Gold Mine Is Costly and Risky
It All Starts With Exploration
16. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Exploration Is Core to Mining
What To Look For
Mining companies and management feel obliged
to find and develop new competitive, low cost
resources, i.e., their Life Blood – to replace
existing reserves – that are diminishing assets –
and to Stay Competitive
MANAGEMENT & INVESTORS BEWARE!
Once a Fido = Dog, Always a Phydeaux
= A Higher Class Dog is Still A Dog!
17. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Why Trained, Qualified Eyes Are Needed
• Best properties are low cost, in stable jurisdictions
& likely expansions/extensions of existing mines
• Top rate management always essential
• Understanding terms and markets critical
• „Resources‟ are concentrations or occurrences of
minerals in such form and quantity and of such
grade or quality that they have reasonable
prospects for economic extraction
• Terms, definitions, methods used to evaluate a
property can vary by user & jurisdiction BEWARE
18. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
In the Best Case: Accepted Resource-Reserve
Classification Systems are Used
Australia JORC Code
Canada CIM 2000 / NI 43-101
Europe PERC
South Africa SAMREC Code
United States SME / SEC Industry Guide 7
Russia A, B, C, D, E
China Traditional and New (1999)
19. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
In the Worst Case: Beware of Fraud
• If it sounds too good, it likely is
• Look for misleading statements
• Know who you are dealing with, etc.
• Evaluate circumstances relative to history
• There is no good substitute for an Independent,
Qualified Expert review – too many variables
and too long a period of time are involved
• Being diligent using Rules of Thumb, Common
Sense, etc. are not good enough
20. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Economic Worthiness of a Property
Is Impacted By Many, Many Variables
Study these and many other items with discerning, trained eye:
• Property Information and Stable Regulatory Environment
• Geology and Resources
• Mining
• Mineral Processing and Metallurgy
• Infrastructure
• Products, Markets and Sales
• Environmental and Permitting
• Financial Issues
• Development Costs and Schedule
• Political and Social Considerations
• Market
• Project Economics – Opex and Capex
22. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Three Levels of Engineering Studies
Used to Define Economic Worthiness
Conceptual Study/Scoping Study
Pre-feasibility Study
Feasibility Study
23. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Engineering Studies – Scoping Study
• aka Conceptual Study, Preliminary Economic Analysis
• First engineering study to compile all elements of a
project into one evaluation and apply economic tests
• Its accuracy is based on first
principles, knowledge, and experience and is
generally +50% / -25%
• This is the least expensive engineering study and is
usually completed in 90 days or less
24. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Engineering Studies – Pre Feasibility Study
• aka PFS or Pre-Feasibility Study
• Accurate to +25% / -15%
• May take 6 to 18 months to complete
• Engineering evaluation applied to key elements, such as
• The caliber of the resource estimate
• The mine design
• The process design
• Mineralogical analysis
• Metallurgical testing
• Soil and rock engineering tests
• Smelting/refining and marketing
• Environmental work – the EIA is completed during the PFS
• Cash flow analysis, sensitivity analyses, and economic tests
25. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Engineering Studies – Feasibility Study
• Feasibility Study or Definitive Study
• The document upon which mine is approved by the
Board of the mining company developing the mine
• If financing is required, this is the document evaluated
by financial institutions in their decision-making process
• The Feasibility Study is also the document to which the
completed and commissioned mine plan is compared to
determine its commercial status
26. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Definition – Feasibility Study
“A comprehensive study of a mineral deposit in which
all geological, engineering, legal, operating,
economic, social, environmental and other relevant
factors are considered in sufficient detail that it
could reasonably serve as the basis for a final
decision by a financial institution to finance the
development of the deposit for mineral production.”
- Canadian National Instrument 43-101
44. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
1. Social Issues/Social License to Operate
• Social, Economic, Regulatory issues are a
leading cause of project delay & cost increases
• Striving to be compliant with regulations and
NGO agitation, etc. are contributing to higher
project costs and delays
• Gaining confidence for Social License to
operate is essential
45. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
2. Costs Control Needed
• Capex rising through cycle
• Capex lags rise in metal prices
• Number of blow ups increasing
• Long investment horizons
• Project development
• Reserve expansion
Per Unit of Annual Production (US$)
Gold $1,250 to $2,500 per oz of annual production
Copper $3.50 to $4.50 per lb of annual production
Capital Costs
46. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Building Mines – Capital Costs
• Capital costs are primarily dependent on
Location, political situation, skilled labor availability
Depth of ore zone and mining horizons
Shaft or adit/ramp access
Plant size
− Shaft size and hoisting capacity
− Equipment fleet size and material handling capacity
− Processing plant capacity to match mining rate
Mining method
− Level of mechanization and automation
− Productivity per man shift
47. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Different Geology; Different Economics
• Of the world‟s gold production the bulk is from
sulphide ore rather than oxide ore
• The project, operating economics are different
• Representative indicative measures:
Sulphide Ore: Capex low grade $300 to
$700+ million; minimum 2 to 5m oz
Oxide Ore: Capex is scalable with Opex =1/5
of Sulphide; minimum scale can be small
48. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
What Can Go Wrong: Issues To Look For
Mine Operating Cost Estimation
• Fuel and electricity costs under estimated
• VAT/sales tax, not included and import duties neglected
• Improper cycle times & haulage distances used
• Mining sequence and methods
• Ground control under estimated
• Inadequate pre-stripping
• Poor haul road design
• Pit slopes
• Dilution
• Poor waste dump design
• Etc.

3. Increased Government Take
• Changing measures and Government „takes‟ at
local, state, and federal levels are today‟s reality
• A global concern – Raises Project Uncertainty
• In normal mining cycles, a project will fail if
Government take exceeds 50%
• Mining companies take all the risk
51. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
4. Access to Capital
• Currently, equity and debt difficult to obtain
• New sources of funding need to be found
• Private Equity, State Owned Enterprises, etc.
may play a larger role
52. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
Recent Capital Markets Trends
• Metals markets in 2012 & 1H13 are turbulent - at best
• A long term perspective is needed in mining business
• Banks, investors and operators are now risk adverse
• Management, stakeholders, employees, partners &
customers need to be realistic about options
• This uncertainty may continue well into 2014
• Alternative and strategic investors, private equity, SWFs
and SOEs may opportunistically step in
53. BEHRE DOLBEAR
founded 1911 MINERALS INDUSTRY ADVISORS
More Consolidation in Mining is Likely
• Valuations are less expensive than greenfield investment
• Consolidation to form Super and Larger Majors is likely
• SOEs, SWFs e.g. Japan, Korea, India likely to continue to
acquire strategic metals and energy fuel resources, etc.
• Strategic M&A may buoy mining assets and share prices
