1. MASTER DRILLING GROUP OVERVIEW

Company Overview

Master Drilling Background and Organogram:

Master Drilling was founded by Mr. Daniel Coenraad Pretorius

in 1986 and commenced raise-boring operations in South Africa

during the same year with two raisebore machines

Today, Master Drilling is one of the global leaders in the

raiseboring market, also providing other specialised drilling

services for mineral exploration and mining companies

Master Drilling currently operates 154 drilling rigs of various

sizes globally, in countries including South Africa, Zambia,

DRC, Burkina Faso, Mexico, Peru, Brazil and Chile

Master Drilling has 94 machines (84 raise borers, 5 drilling

related rigs and 5 blast hole / sampling rigs) active across its

operations in Africa and South America. This is one of the

largest fleets of raisebore machines globally

Master Drilling expanded into exploration drilling during 2005 by

acquiring a controlling stake in Drillcorp Africa (Pty) Ltd

(“Drillcorp”)

Drillcorp has a total of 60 exploration drilling rigs in operation

across numerous countries in sub-Saharan Africa, including

Burkina Faso, Zambia and DRC. These rigs include both

surface and underground diamond drill and reverse circulation

rigs

Master Drilling’s head office is located in Fochville, South

Africa. An engineering facility, which manufactures most of the

consumables and parts for the world fleet, is housed within the

same complex

Raisebore Drilling Overview

Raisebore Drilling – The Safer, Faster and More Accurate Method of Drilling:

Raisebore drilling is a method used to drill ore passes and

ventilation shafts required for production in an underground

mine, without the use of explosives

The raisebore drilling machine is set up on the upper level of

the two levels to be connected. A small pilot hole (c. 300mm in

diameter) is drilled to the level required. The pilot hole is then

reamed to a larger diameter (up to 6m in diameter) by attaching

a reamer head to the drillrods at the lower shaft and pulling it

back towards the drilling unit in a circular motion

The reamer head has a series of tungsten carbide cutters which

cut the rock during the circular motion. The drill cuttings from

the reamer head fall to the floor of the lower level and are

removed by a standard LHD loader

The boring principle is attractive because it offers the following

advantages over conventional drilling and blasting methods:

–Safer working conditions

–Speed of completion

–A hole which has a more stable structural shape

–A hole which has smooth sidewalls which has low

frictional loss in ventilation airways, and reduces the

likelihood of blockages in the ore-passes

SERVICES

Niche drilling segment used extensively in on-mine development

(ventilation shafts and ore passes) by exiting producers

Raise bore drilling is highly differentiated to exploration drilling; it is

insulated from mining capital cycle (customers are major miners in

production not explorers), benefits from rising safety standards (increased

ventilation shafts) and increasing mining capital intensity (customers

seeking to extend existing operations rather than build new mines)

3. CORPORATE STRATEGY

SWOT Analysis

S Established client base among blue chip mining companies

Pioneer and market leader in technically specialised raisebore

drilling – creates competitive advantage vs. competitors

Primary focus on production-stage drilling – less influenced by

commodity price swings and/or capital market uncertainty

Contracts signed up to 1-2 years in advance of service delivery,

enabling high degree of future earnings visibility

Large fleet of specialised drill rigs, including one of the world’s

largest raisebore machines (HG380)

STRENGTHS:

OPPORTUNITIES:

O Expand geographical footprint to new target markets (Colombia,

DRC, Mali, Australia)

New technology development (Gripper – horizontal drilling)

Diversification into new market segments, including hydro

schemes (well drilling) and civil engineering

Improved brand recognition, both within mining industry and

amongst institutional capital market participants

Strategic and opportunistic acquisitions in new markets

W High quality, specialised raisebore services charged at premium

price point relative to competitors

High average fleet age

Lack of enterprise-wide IT platform (currently being addressed)

Low BBBEE score of local South African business – reduces

competitiveness when tendering for South African government

contracts

WEAKNESSES:

THREATS:

T Shortage of skilled labour inhibits rate of expansion (mineral

drilling more technically advanced skill than oil/gas, requiring

approx. 3 – 4 years to train supervisory/lead driller)

Exchange rate fluctuations for international operations

Closure of client mines caused by commodity price weakness,

capital shortage or other factors

Cash flow constraints inhibit ability to deliver on contracts

Deterioration in government relations in key markets

Sustained long-term capital market weakness

4. MAJOR CLIENTS & COMMODITIES

Commodity Focus

Overview of MD Group Commodity Focus: MD Group Revenues by Commodity (2011 / 2012H1):

Master Drilling enjoys a degree of diversification through its

relative balance between precious and base metals exposure:

Gold & Silver: increasingly driven by investment demand

as safe haven and hedge against US dollar inflation

PGMs: remain subject to developed market demand,

particularly EU automobile consumption

Base Metals: remain vital to urbanisation and

industrialisation of BRICs and other emerging markets

In light of recent commodity price volatility, the Company’s

management has identified commodity diversification as a high

priority short-term focus area

In particular, Master Drilling is targeting revenue growth and

diversification in the coal, iron ore and ferroalloys (chrome,

manganese) sectors in South Africa

Iron ore and ferroalloys exposure will provide cyclical

diversification, as steel is an early-cycle industry vs. precious

metals and PGMs (typically late-cycle)

Additionally, the Company seeks to expand service offering in

the civil engineering sector, particularly for underground

development at large hydro-electric projects

Outlook on Drilling Services Market

Page 33

7. OUTLOOK ON DRILLING SERVICES MARKET

Overview of Drilling Services Industry

Market correlated to commodity prices & capital markets:

Exploration and development drilling are highly correlated to

commodity prices, mining company equity financings, mining

acquisitions and mine site activity

Drilling services demand for production-stage clients is considerably

less volatile than exploration/development clients due to lower

dependence on commodity prices and equity market financing

Exploration budgets of both senior and early-stage exploration

companies are key leading indicators of global demand for drilling

services

In 2008, high commodity prices drove exploration activity to record

highs with global exploration spending approaching US$14 billion

During the global economic slowdown of 2009, mineral exploration

expenditures fell by over 40%, but have since recovered

Funding for junior miners dried up during financial crisis, resulting in

delay or cancellation of many pre-production mining projects globally

Current outlook for gold and base metal exploration is positive, as

emerging markets continue to drive global demand for commodities

Mineral reserves of both precious and base metals have been

increasingly depleted during the past decade

Reduction in both mine lives and mined grade likely to lead to an

extended recovery in exploration and development activity

Focussed on discovery of new

High volatility due to dependence

Initial establishment of mine

infrastructure, including tunnels,

ventilation shafts, dewatering

systems and ore passes

Continued core drilling for accurate

definition of geological conditions

Tends to be high margin

Multiple purposes, including

establishment or expansion or

ventilation shafts and ore passes

Typically undertaken for majors

and established mining

companies, resulting in greater

contract frequency and reliability
