Measured and Indicated ("M&I") resources amounted to 14Moz at year-end 2018, up 0.9Moz or 7% over the previous year, as mine depletion was more than offset by the maiden resources delineated.

Rescuers hope to find him at a depth of 236 feet, where a soil blockage has hampered efforts to save him.

Both founders told me they expect to reap enormous cost reductions from expanding production — activities that involve buying materials more cheaply in bulk and assembling units on automated factory lines instead of building them by hand, as is the case now. Design advances could wring out other costs. “Maintenance is very expensive,” Wurzbacher said. “Right now, if we exchange the filters in the collectors, we have to rent a crane, and that’s a lot of man-hours. In the next-generation units, we have improved that a lot, so relatively small design changes could cut the costs of maintenance by a factor of three.” Climeworks also intends to derive savings from improvements to crucial materials, like the sorbent that catches the CO₂. At the moment, the company’s technology requires that the temperature inside the units be raised periodically to about 100 degrees Celsius to release CO₂ from the sorbent so it can be drawn off and stored. If the process can be done at a lower temperature, the units will use less energy, and the life of the materials should be extended, further driving down costs.

In all honesty, I am still not sure if I like the base design. It certainly looks modern, but it walks the line of being a little busy for my taste. Regardless, I appreciate that Topps tried something new.

He confirms that these developments prompted Booysen Bore to replace all their MK I machines which at one stage totalled 16, to MK II units, when they reached the end of their life span. He also notes Atlas Copco’s assistance with the conversion of a ROC10 MK II to an RC (Reverse Circulation) machine for exploration drilling.

Rescuers had found that the borehole – 100m deep and just 25cm wide – was blocked with earth, raising fears that soil had collapsed onto the child.

In 2019, Hounde will continue to be the priority exploration focus for Endeavour with a budget of up to $17 million totaling approximately 195,000 meters of drilling with the aim of:

When the three-foot rod is completely submerged in the dirt, operators disconnect the rod, spin the bar back up and connect another segment onto the drill.

Today Is the Day — a band that comprises Nashville-based musician Steve Austin and whoever happens to back him at the time (including members of Mastodon at one point) — have long bridged the gap between metal and the rusty lead-pipe subtlety of Amphetamine Reptile-style noise rock, and in fact have released records through both AmRep and Relapse. Naturally, their sound always felt considerably heavier than the former, but much too weird to fit in with the latter. “Kill Yourself,” a standout among the many tracks on the band’s peak, Temple Of The Morning Star, is rife with ugliness and misanthropy, as well as Austin’s penchant for prog-influenced Fripp-ery and effects-pedal pranksterism. The sound is wild and slightly disorienting but ahead of its time, the sounds showcased here predicting similarly intense experiments from the likes of Botch and Daughters.
