The flow of water pumped into the borehole through the bedrock fissures will be closely monitored. The water pressure will enlarge the fissures, with geophones detecting micro-vibrations that reveal the direction in which the water is passing through the bedrock. Several geophones have been installed, with the deepest at depths of 1.2 and 1.1 kilometres, one at a depth of 670 metres, and the rest at depths of more than 300 metres at various locations in the Helsinki Metropolitan Area.

Colombia’s President, Iván Duque, has stated that the peace talks with the guerrilla group ELN. He had set the arrest warrants against ten ELN negotiator, who had participated in peace talks in Cuba, is back in force, said Duque on Friday. Previously, the government had made the guerrilla group for a bomb attack on a police Academy in Bogota, responsible for the on Thursday, at least 21 people were killed and 68 more were injured.

Brosseau recommends that the team meet with Joe Landry, an expert in manuscript restoration, so they travel to the School of Art and Design in Halifax where Joe examines the scraps under a microscope. Unable to determine anything conclusive, he soaks both paper fragments in water to see if there is any writing visible.

- In 2018, Endeavour issued a $330 million convertible note and subsequently downsized its $500 million revolving credit facility to $350 million.

IN: Ruan Ackermann (Lions), Fraser Balmain (Leicester Tigers), Gareth Denman (Northampton Saints), Jake Polledri (Hartpury RFC), Ed Slater (Leicester Tigers), Owen Williams (Leicester Tigers), Jason Woodward (Bristol Rugby), Ben Vellacott (Academy), Freddie Clarke (Academy), Lloyd Evans (Academy).

AISC amounted to $564/oz, well below the guided $580-630/oz range due to the outperformance of the operation and a lower than planned strip ratio in the second of half the year following a shift in the mine plan which delayed higher stripping to 2019.

This truck is a double-taker, for sure. Whether it’s the Tiffany blue paint that glows brilliantly against the asphalt, the side dump exhaust that pops out of the fender right behind the front wheel well or the massive sheet metal wheel wells stamped with lightening holes above each tire – you almost can’t look at it hard enough! What’s most intriguing, however, might be the engine sitting in between those gargantuan wheel wells – it’s a twin-turboed LS1 with LS6 heads; a complete Holley Dominator management system handles the boring stuff so you can focus on doing nothing but looking incredibly cool because (for once) all eyes are upon you!

Woskov, a senior research engineer at MIT’s Plasma Science and Fusion Center (PSFC), is using a gyrotron, a specialized radio-frequency (RF) wave generator developed for fusion research, to explore how millimeter RF waves can open holes through hard rock by melting or vaporizing it. Penetrating deep into hard rock is necessary to access virtually limitless geothermal energy resources, to mine precious metals, or explore new options for nuclear waste storage. But it is a difficult and expensive process, and today’s mechanical drilling technology has limitations. Woskov believes that powerful millimeter-wave sources could increase deep hard rock penetration rates by more than ten times at lower cost over current mechanical drilling systems, while providing other practical benefits.

- The identification of mineralization in the Le Plaque area where drilling is ongoing and a resource is expected to be delineated in Q2-2019.

Borehole or down-hole methods are of two distinct varieties: borehole seismic and wireline logging. The former is achieved when seismic receivers are used to acquire information in the borehole, presented as a vertical seismic profile (VSP).  VSP in most cases, is integrated with surface seismic information. A successful example of this method is the use for mine planning, and harnessing deposits of uranium in northern Saskatchewan, Canada. Conversely, the latter is when a logging tool called ‘sonde’ is used in the vicinity of the borehole. The information obtained are presented as Logs; a plot of the measured physical property versus depth. In a basic sense, well logs help to identify and quantify minerals.

Atlas Copco Secoroc’s COP 66 hammer and its new platform design represent real innovation in down the hole drilling.

The thing about 1,000hp is that when you have it, everybody wants to see how you do it. Everybody wants to know what quadruple-digit horsepower numbers look like in a physical iteration of a powerhouse.
