Hi Renae,

First, I think your title of ‘Customer Happiness Leader’ is brilliant. I am a huge believer in customer service and anyone in that field, should aim to please their customers across all dimensions of customer service.

I enjoy Dynamics G-Ex as a supplier because you reply to all enquiries promptly and go to lengths to find items I’ve queried. One of your key differences is your delivery times, I believe you express post and whatever I order, is here in a couple of days! Which for us is excellent because we are so remote. Your communication is always friendly and professional. Keep it up!

Hi Curt,

Yes the medium abrasive blades offer the best value as they will cut the hard core we have & don’t wear as quickly, we generally get 350mts plus from these blades, they seem to have a thicker matrix than the ‘Xxxxx’ blades & definitely last longer.

Blackham Resources Limited

Hi Curt,

Feedback from our drillers re the new trays is they prefer them compared to others as they are much easier to pick up and move about.

Dynamics are proud to stand shoulder to shoulder with our team. Together, the company is working on a culture where our people wake up each day inspired to come to work, improve what they do every day and return home at the end of the day, fulfilled by the work they do.

Dynamics operate in a demanding, high-pressure environment but work just as hard to make our workplace fun and welcoming -- like a family away from home.

The company strives to build a better place to work, so our employees can truly feel engaged and have fun at work, while doing what they love. Every day our employees fix what bugs them, and everyday, we are honoured by this opportunity to empower geologists and fieldies.

Our people are dedicated in caring for our customers and taking ownership of the situations they find themselves in. Dynamics knows, if it takes care of it's people, our people will take care of our customers and our customers will take care of our brand.


We believe that mining and geology professionals have the natural desire to spend their days out in the great outdoors -- to search, explore and define the next big deposit that will become a great prosperous mine.

We believe in getting these great people, wherever they are in the world, from behind their desks, out of their offices and into the field so that they can unearth the next big discovery! And when they get there, we make their lives easier by supplying the best and easiest-to-use geological tools, products and industrial mining equipment.

We believe in always giving our very best. We never compromise on product quality, safety or service. Our clients know that whenever they need the best product, they can rely on us to deliver it. We believe in long-term and sustainable growth -- not just for us, but more importantly, for all the hardworking mining and geology professionals we serve.

Great Culture = Great People & Passion

Hi Sean.

We originally purchased a Core saw from ‘Xxxxx’ for our operation in PNG. It turned out to be unsuitable for broken and fractured rock. The Dynosaw was then purchased and shipped to PNG and has operated without any issue in a tough terrain since 2014. We prefer the Dynosaw.

# Note Dynosaw brand has been superseded by the Discoverer Brand, nothing changes about the build quality or manufacture process.

Mindarie Operations | Murray Zircon Pty Ltd

The bags look good – the ProFab Bag numbering is very clear and appears to be very durable. The bags appear consistent in their quality, and they are of a good quality (tough, well woven with good stitching), the side tie strings are also tough and do not appear to break easily. Overall very pleased so far.

Dynamics have been excellent to work with, and provided us quality kit when we needed it – they are also very good at following up on any concerns you may have with their service.

They do a very good core tray system also, quite portable, may save some core handling issues.

We have recently switched over to Dynamics to supply our wooden stakes after briefly trialling them at site. The quality was immediately noticeable, and we found that the withstood the rigours of open cut mining perfectly, particularly in hard rock. Our previous supply of pegs were evidently cheaper, however, with up to 50% of them breaking when used, it was obvious that cheaper isn’t always better, especially when you’re throwing half of them away. We have factored this in, and with the price only being marginally more, it made sense to pay a little more for a product that was far superior and in the long run actually more cost effective.

Below are some, snaps of the pegs we were using previously. In this particular photo, out of the 50 pegs we had to use almost all of them snapped, splintered or shattered to pieces when knocked in.
