On the 8th of January 1740, the Dutch East India Company (VOC) ship
Rooswijk weighed anchor and left harbour on the Dutch island of Texel, carrying a varied cargo that included large quantities of silver coins and bullion intended for trade. This marked the start of what would have been an arduous 9-12-month long journey to Batavia, the then capital of the former Dutch East Indies (now Jakarta, Indonesia). However, by the next day
Rooswijk had been driven onto the Goodwin Sands off the coast of Kent and subsequently broke up – sinking with no survivors. Passing into obscurity, it was not until 2005 that the ship was re-discovered following a search by recreational diver Ken Welling.
Studying the Structure of Pores in a Shale Reservoir
At odds with traditional energy resources, experimental energy resources such as Shale Oil, Shale Gas, Tight Oil, Tight Gas, and Methane Gas in a coal bed are distributed extensively in the tiny cracks and fissures of a shale reservoir, known as grikes.
In preparation for increasing the recovery rate of atypical energy resources, it is crucial to carefully examine the structure of the fine pores in the shale reservoir.
Using a Scanning Electron Microscope (SEM), mineral distribution and pore structure can be observed in the mechanically polished slice of a specimen from a traditional reservoir.
JEOL Introduces New Configuration of Its Broad Ion Beam Milling Cross Section
JEOL USA introduces a new configuration of its bestselling broad ion beam milling instrument, the Cross-section Polisher (CP). The CP is widely used for preparing pristine samples prior to high-resolution imaging and elemental analysis with the Scanning Electron Microscope (SEM). The upgraded configuration includes high-speed milling, sputter coating, cryo-preparation (down to LN2 temperature), and air-isolated transfer for atmosphere-sensitive specimens (for example Li batteries).
Traditional mechanical preparation of specimen surfaces for SEM imaging can introduce various artifacts, such as scratches and embedded polishing media, that obscure the original microstructure, crystallographic information, and precise layer thickness measurements. Broad ion beam polishing using the JEOL cross-section polisher (CP) offers pristine surface preparation with minimal artifacts. The JEOL CP is a tabletop instrument
BASE RESOURCES LIMITED - Kwale North and Bumamani Resources Estimates

Key Points
As part of the pre-feasibility study currently underway to assess the viability of mining the Kwale North Dune and Bumamani deposits, seeking to extend the mine life of Kwale Operations, additional drilling and mineralogy assessments have been conducted.
The Kwale North Dune Mineral Resources estimate has increased by 13% to 194 million tonnes at an average HM grade of 1.5%, containing 2.9Mt HM, based on a 1% HM cut-off grade.
99% of the Kwale North Dune Mineral Resources estimate is now reported in the Measured and Indicated categories.
The maiden Bumamani Mineral Resources estimate is 5.9 million tonnes at an average HM grade of 1.9%, containing 0.115Mt HM, based on a 1% HM cut-off grade.
