Bellevue Gold Ltd has set ambitious production targets and exploration goals for its gold mine in Bellevue. The company plans to process 1 million tons of ore to produce 165,000-180,000 ounces of gold in FY25. The rising price of gold is expected to help Bellevue maintain wide profit margins. The company also aims to increase its production to 250,000 ounces per year by 2028, which would place it among the top-tier gold projects globally. Bellevue is focusing on development rates, grade control, and exploration to achieve its goals. The company has raised $150 million in capital and is committed to funding exploration projects to ensure the future of the gold industry. [Extracted from the article]

The article reports on the guidelines issued by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) for proper operation of heating, ventilation and air-conditioning (HVAC) system in commercial and educational buildings to help control the spread of COVID-19 through airborne respiratory droplets. The guidelines focus on electronic air cleaners, ventilation, and filtration efficiency.

The article focuses on Aoife Nile, a special 10M picnic cruiser designed by Nigel Irens. It mentions the boat struggles to displace more water than the laws of hydrodynamics allow. It also mentions that in the early 2000s, Irens started applying lessons from multihull design to monohull powerboats with models that carry limited mass on as long a waterline hull as possible.

A recent study conducted by the National Institute for Occupational Safety and Health (NIOSH) examined the potential risks associated with unconventional shale well drilling intersecting with mining resources. The researchers found that the drilling process could lead to gas migration into the mine, posing a significant threat to the health and safety of underground workers. To better understand the distribution of gas within the mine and the effectiveness of the ventilation system, the researchers utilized network software to model mine ventilation. The study concluded that a standard Pittsburgh coal seam longwall ventilation scheme could effectively dilute a significant inflow of methane. [Extracted from the article]

The Overture system includes three parts: a room sensor ($425), a wall control ($320), and a smart plug ($120). To monitor the air quality in a whole house, you'll probably want a few different room sensors, as well as wall controls near the kitchen and bathroom exhaust fans. The wall control also has built-in sensors and connects directly to ventilation fans and/or range hoods in rooms such as the kitchen, bathroom, and laundry room, and will turn them on until air quality improves.
