Introduction The excavation or drilling in rocks becomes extremely complicated when working in confined spaces and if you need to drill holes with large diameters. Often the length and diameter of these perforations becomes impracticable due to the cost of time and labor. In view of these problems, a simple, compact and really solution was […]

The Tau Tona Gold mine in South Africa was extended to a depth of 3.9km in 2008, making it the world’s deepest mine at that time. The name TauTona means ‘great lion’ in Setswana (“TauTona Gold Mine, Anglo Gold, South Africa,” n.d.). The mine was located at on the West Wits line, south of Carletonville, […]

Gold prices climbed to their highest level in nearly 11 weeks on Tuesday as the U.S. dollar slumped following President Donald Trump’s inauguration and investors sought the safe-haven metal to hedge against uncertainty sparked by his tariff plans. Spot gold climbed 0.7% to $2,725.70 per ounce by 0804 GMT and hit its highest since Nov. […]

Tin falls back to earth but supply problems haven’t gone away Investors lost faith in tin’s bull narrative towards the end of 2024, slashing bets on a further rally and helping crash the price. Tin had been the star performer among the London Metal Exchange (LME) base metals pack until then with year-to-date gains of […]

This is a paper from (Gandhi & Sarkar, 2016). Geophysics is becoming an increasingly important discovery tool as exploration moves deeper into subsurface. The ability to rapidly iterate and combine data and constrain odels within project timelines is essential for making geophysical modeling a more practical and reliable aid. As explorationists are compelled to look […]

Gold held firm near a five-week high on Friday and was set for a third straight week of gains, as U.S. inflation data released earlier this week raised expectation that the Federal Reserve might cut interest rates further this year. Spot gold was flat at $2,715.09 per ounce, as of 0332 GMT. Bullion has gained […]

Introduction Borehole geophysics is the science of recording and analysing measurements of physical properties made in wells or test holes (Borehole Geophysics | U.S. Geological Survey, n.d.).  Continuous or point data is obtained using probes and processed to produce geophysical logs. The geophysical responses from targets buried in the earth decrease with increasing depth of […]
