- New Brunswick Shaft successfully inspected by underwater remote operated vehicle.
- Existing mine shaft and timberwork appear to be in good condition to depth.
- Recent exploration drill intercept on Brunswick #1 Vein is located near the existing shaft.
Vancouver, British Columbia--(Newsfile Corp. - February 20, 2018) - Rise Gold Corp. (CSE: RISE) (OTCQB: RYES) ("Rise" or the "Company") is pleased to announce it has successfully completed an initial underwater inspection of the New Brunswick mine shaft.
The Company previously announced the assay results from drill hole B-17-01 ("the Drillhole"), the first drill hole of the exploration drilling program at the Idaho-Maryland ("I-M") Gold Project (see Rise news release of Jan. 3, 2018). The Drillhole intersected the Brunswick #1 Vein approximately 50 m below the B1600 level at a depth of ~540 m below surface and assayed 12.2 gpt gold over 14.9 m (7.8 m est. true width) including 63 gpt gold over 2.7 m (1.4 m est. true width).
This drill intercept at the Brunswick #1 Vein raises the possibility that there could be substantial gold mineralization in the developed upper levels of the mine near the existing mine shaft.
To support additional drill testing of the new exploration target at the Brunswick #1 Vein, the Company conducted an underwater survey of the existing New Brunswick vertical mine shaft in mid-February. The objective of this survey was to determine the current condition of the shaft which the Company believes is a valuable component of the I-M project.
NEW BRUNSWICK SHAFT SURVEY
The Company believes the existing New Brunswick vertical mine shaft (the "NB Shaft") is a valuable component of the I-M project. The I-M mine is currently flooded and the Company completed an initial inspection of the shaft to determine its condition.
The NB Shaft was the primary entry and hoist for the historic production at the Idaho-Maryland Mine. The NB Shaft extends to a depth of 3400 ft (1036 m) below surface and connects to all major levels of the I-M Mine. The NB shaft consist of three timbered compartments and had historic skipping capacity of ~75 tons/hour using 6 ton skips and hoisting speed of 1250 feet per minute. There is potential to increase hoisting capacity further by using larger skips and increasing the hoisting speed.
The Company engaged Advanced Marine Services Corp. ("AMS"), from Lake Tahoe, California to conduct a preliminary inspection of the New Brunswick Shaft. AMS used a Seabotics LBV-300 remote operated vehicle ("ROV") to survey the shaft down to a depth of ~760 ft (232 m). The ROV filmed the timberwork and center compartment of the shaft and entered the B580 level shaft station. The ROV survey confirmed that the NB Shaft remains open and the timberwork and guides appear to be in good condition to the depth surveyed. AMS subsequently tested the shaft to 2300 ft (701 m) with a weight and winch cable and the shaft is confirmed to remain open to at least this depth.
The Company believes it is likely that the submerged timberwork has been preserved. Decay, or rot, of wood by fungus requires the presence of oxygen. Recent field testing of water quality from the New Brunswick Shaft consistently demonstrate very low oxygen levels and strongly reducing conditions within the water. The reducing conditions and low oxygen levels indicate that wood mine timbers present below the water surface within the mine workings should not be susceptible to rotting.
The successful survey of the shaft allows the planning of future underwater inspections using an ROV capable of reaching the deepest levels of the shaft. Future ROV inspections could include the inspection of the shaft to the full depth of 3400 ft, inspections of mine levels, and core testing of the wooden timberwork to prove its structural strength for engineering studies.
The Company has added photos and video of the shaft survey to its website at .
The Company expects to provide further updates on the planned exploration drilling program at the Idaho-Maryland mine over the coming weeks.
