- Despite plans to mine higher grade ore, the average processed grade is expected to remain fairly flat over 2019 due to the use of lower-grade stockpiles. This marks a change compared to the previous mine plan due to the company’s strategic focus on maximizing free cash flow generation and reducing working capital.

Once destined for Mars, a prototype drill has a new mission: To bore into rocks buried deep beneath the ice in Antarctica.

We also take great pride in taking it all a step further by developing faster and more efficient grinding machines so that our customers can make the absolute most of our drill bits. Worn down button bits will slow down the whole drilling operation with escalating working hours and rig running costs as a direct consequence. Rapidly reground drill bits reduce the overall drilling costs by up to 30 percent. Grinding is therefore essential for productivity.

Both the boreholes at his 350-acre Hendy farm ran down to a trickle in mid June. For five weeks Aled and son Osian have been making round trips to a nearby river with a tanker lent by a local dealership.

Having worked in the independent water supply industry for over 25 years, Envireau has worked on projects involving new and historic boreholes all over the UK and across the globe; yet often, the most surprising aspect upon arriving at a new site for the first time is to learn how little a company knows about their water supply. The engineering manager knows exactly how water is used in the processes; the quality of water required is understood; but few question the age of the borehole, depth, diameter and water levels. The secret, underground world of the borehole is often regarded as a black art; best left alone.

As detailed in the table below, sustaining and non-sustaining capital allocations for 2019 amount to $68 million and $83 million respectively. Growth projects amount to $64 million, mainly for the completion of the Ity CIL project construction. More details on individual mine capital expenditures have been provided in the above sections.

- Processing unit costs decreased from $8.46 to $7.41 per tonne due to higher stacked tonnes and lower reagent consumption for oxide material processed.

- Tonnes of ore mined increased as mining activities ramped up following the end of the rainy season. Activities focused exclusively on mining oxide ore from the Kao pit.

Mincon’s balance sheet remains strong with net assets of €97.9 million and net cash of approximately €38.6 million available for investment.

“The absolute limits of life on Earth in terms of temperature, pressure, and energy availability have yet to be found,” they say, in an accompanying press release. This also neatly lends itself to the field of astrobiology, whose researchers – searching for life beneath, for example, Mars and Enceladus – are comforted by the notion that even in the most bizarre environments of Earth, life finds a way.

Drill core (PQ, HQ and NQ size) samples were selected by Endeavour geologists and sawn in half with a diamond blade at the project site. Half of the core was retained at the site for reference purposes. Sample intervals were generally one metre in length.
