"Master Drilling is pleased to report a resilient first six months of 2024, achieving USD127.0 million in revenue, reflecting a 17.3% increase
compared to the same period in the prior year.
This accomplishment comes amidst a backdrop of global market and economic uncertainty.

capital allocation, and operational excellence."

Financial Overview

Revenue increased 17.3% to USD127.0 million and operating profit decreased by 67.6% to USD6.9 million due to impairment losses recognised on
reverse circulation and mobile tunnelboring equipment. These figures represent resilient results, despite uncertain market, economic and operating
conditions experienced globally.

The impairment of property, plant and equipment is the main driver in an overall decrease in profit after taxation of 75.1% to USD3.6 million.

USD earnings per share (EPS) decreased 78.7% to 2.0 cents, and ZAR EPS decreased 78,1% to 37,5 cents. USD headline earnings per share (HEPS)
decreased 3.2% to 9.0 cents, and ZAR HEPS decreased 0,5% to 168,6 cents.

Net cash generated from operations amounted to USD27.7 million. Cash resources continue to be managed carefully to cater for emerging opportunities
that require specific design, planning, and investment.

Master Drilling's total capital spend of USD19.7 million was applied as follows: 55% on expansion and 45% on sustaining the existing fleet.

Debt increased from USD44.1 million to USD46.0 million and the gearing ratio, including cash, decreased slightly from 6.9% to 6.8% in the
first six months of the 2024 fiscal year.

Operational Overview

Safety and response to risk

The Group has an extensive risk management program, and this is made visible through a collaborative platform. Progress on the implementation
of mitigation measures is tracked and significant business risk is escalated to the executive team and Board. A group of internal auditors
provides assurance that actions are followed through and have the desired effect.

Our Lost Time Injury Frequency Rate for 2024 increased to 0.84 because of 4 Lost Time Injuries which occurred in the first half of the year.
Detailed investigations were conducted into the incidents and specific entities were identified for further safety intervention plans.
Key initiatives such as behavior-based safety, a revised learning and development strategy and observational safety will be maintained for
the remainder of 2024 along with the intervention plans per area. Our priority remains to move people out of harm's way through innovative
engineering solutions.

Throughout the year, the Group implemented a rigorous programme adhering to applicable ISO standards by reviewing existing protocols, implementing
new hazard identification measures, and providing focusing on the upskilling and re-skilling of individuals within the organization.

South America

Notwithstanding several operational challenges throughout this region, there were positive developments. Despite identified loss making projects
having a negative impact on financial performance, machine utilization rose across the board. Key projects with important clients continued to
move forward, with negotiations underway for extensions and new contracts. In one of the countries, production saw a significant rebound, reaching
its highest level in several years. This region is also expanding its service offerings and expects to recover revenue to pre-restructuring levels
that occurred in the current and previous years.

Central and North America

This year has been a productive and successful one for us in the region. Despite not performing soundly financially speaking, we have obtained
key permits allowing us to expand our service offerings not only in this region but potentially to neighboring regions. Our intensive investment
in marketing by visiting several potential clients in the area paid off as we have secured a couple of new contracts across multiple mines.
We are well positioned for continued growth, with a strong pipeline of opportunities and with an anticipated increase in pricing requests expected
from clients in this region.

Africa

Africa has been a stronghold for the Group in the past few years and the current year was no exception. The Group continues to see Africa as
a key market for growth and is actively looking for new business opportunities. The Group has a strong presence in several African countries
with ongoing projects and good client relationships. The Group is aware of the risks in the mining sector in this region but will continue to
support its loyal clients and is also optimistic about future opportunities in other African countries.

Rest of the World

This region performed well so far in 2024, exceeding expectations on profitability. This was achieved through efficient use of staff,
cost-control measures, and successful project execution. Business is expanding into other areas. New contracts were secured to provide
multiple machines and services for growing clients. Additionally, a challenging project is being used to develop innovative drilling methods
that might result in additional service offerings by the Group in the future. The long-term contract within this region is performing
in line with expectations.

Slim drilling

This business update highlights activity across various drilling and exploration services. In the platinum mining sector, dewatering operations
have been paused due to cost-cutting measures. The freed-up equipment is available for deployment on new projects. Drilling operations have
also begun at a new client with two newer technological machines, and satisfactory penetration rates have been achieved thus far. These operations
are expected to ramp up in the second half of 2024.

Finally, the Group is excited about its technology projects. The underground robotic machine has been successfully deployed and is currently
undergoing performance evaluation. All indications' looks very good and the possibility to approve the building of the second underground
robotic machines.

For the Surface drilling the robotic rig, Desert Elephant Hydraulic commissioning completed during July 2024. Robot interface programming
is planned for the latter part of August 2024. Hard drill testing will be conducted beginning September 2024. Progress is satisfactory and
in time for upcoming proposals.

Other mining services

The Group's other mining service companies are currently out-performing expectations, with its strong focus on improving a safe working
environment for our clients' employees. The service offerings have been expanded outside the South African borders with the potential
to further expand globally, being persuaded during 2024 and beyond.

Technology

Master Drilling is committed to continuous technological advancement as a key driver of client value and market competitiveness.
To achieve this, we have implemented a focused strategy that leverages targeted investments across our various divisions:

- Diversification and Profitability: We are actively expanding our service offerings with innovative solutions designed to address
  specific client needs. This includes the development of:

    - Raise Boring: Additional XXL capacity rigs, including RD8 and RD7 1000 models, will be operational in 2024, enhancing our
      deep-drilling capabilities. The completion of the first LP 100 mobile slot borer further strengthens our portfolio.
    - Exploration Drilling: The industry-leading RUCDR rig has been successfully deployed in South Africa, demonstrating our
      commitment to robotic solutions. Furthermore, the development of a robotic surface core drilling rig for deep-hole

    - A&R Company: The successful testing of our Scraper Winch Proximity Detection and Missing Person Locator products paves the way
      for wider industry adoption in 2024.
    - AVA Company: We are developing an integrated, OEM-independent underground fleet management solution, while continuing global
      expansion of our established surface solution.

By investing in these cutting-edge technologies, Master Drilling is positioned to deliver safer, more productive, and cost-competitive
solutions for our global client base, optimising mineral recovery and information management throughout the mining lifecycle.
Operational equipment

The fleet consists of 140 raise bore, 53 slim drilling and one mobile tunnel boring rigs. The total raise boring fleet utilisation
rate was around 75% while the slim drilling fleet utilisation was around 25%. The rate of new rigs coming on board will settle with
a focus on larger units, which typically generate higher income.

Impairment of property, plant and equipment

Shaft Reverse Circulation Equipment

The Reverse Circulation equipment in the Group's North and Central American operations is currently not utilised due to a
decline in the relevant market. The Group has therefore provided for impairment losses on this equipment while it looks to market
the equipment elsewhere in the world.

Mobile Tunnel Boring Machine

The Group has furthermore provided for an impairment loss on the Mobile Tunnel Boring Machine as no formal agreement is currently
in place to project future cash flows, due to uncertainty over commodity prices within the machine's target industry.

Outlook and prospects

Even in the face of global uncertainty, Master Drilling is confident in its ability to perform well. This confidence stems
from several factors. First, our long-term contracts provide a stable foundation for our business. Second, we have deliberately
diversified our footprint across various regions, commodities, currencies, and industries. This strategic approach mitigates risk
and positions us for success in a complex global environment. Proactive capital management is another key strength, ensuring
we efficiently allocate resources to maximize returns. Finally, our unwavering service orientation keeps client needs at the
forefront of everything we do.

remains a core principle that guides our decisions. Our diversification strategy, encompassing regions, commodities, currencies,
and industries, has proven its worth and will continue to be a central pillar of our growth plan.

The pipeline as at 30 June 2024 totalled USD599.6 million, while the committed order book totalled USD271.4 million for the
remainder of 2024 and beyond. In the short to medium term, the sales pipeline is expected to stabilise and increase with further
tactical acquisitions and joint ventures supporting performance.

Looking towards the future, Master Drilling prioritizes both safety and innovation. We are strong advocates for utilizing advanced,
mechanized equipment, which aligns perfectly with the industry's growing focus on automation and remote operations. This commitment
to cutting-edge technology positions us competitively within this evolving landscape. Furthermore, we actively explore opportunities
to expand beyond traditional drilling, with potential applications for artificial intelligence being a key area of interest.

Investing in our people is another cornerstone of our success. We are committed to attracting and retaining top talent by fostering
a positive work environment and implementing best practices in human capital management. Finally, Master Drilling takes Environmental,
Social, and Governance initiatives very seriously. We believe that strong practices not only align with our values but also ensure
