About Our Presentation
Characterization of In Situ Saturation Profile Through Tube Measurements and SCPTu.
Ezra Coyle, PE | Monday, February 24 at 15:25 MST
As more scrutiny is given to upstream tailings facility’s liquefaction potential and resulting strengths around the world, saturation of the tailings becomes an important question for tailings practitioners, especially in conditions of near, but not fully saturated tailings. The difference in seismic behavior between near, but not fully saturated and fully saturated tailings can have significant implications in the stability outcomes and design configurations for tailings storage facilities. This paper presents a unique and extensive site investigation performed at an Australian gold mine upstream tailings facility, in predominantly near (but not fully) saturated tailings. The paper presents the method and results obtained by direct measurement of Sr through the collection of 100 high-quality piston tubes to full depth of the tailings column, that were then used to determine void and saturation ratios. The tubes were supplemented with adjacent SCPTu dynamic Pore Water Pressure (PwP) and profiles of Compression wave velocity (Vp) and shea.
Gold Property Transaction Values and Gold Price (2012-2024)
Grant Malensek | Tuesday, February 25 at 9:45 MST and at 14:05 MST as part of World Gold 2025
SLR has tracked transactions on gold properties worldwide from 2012 to 2024. For comparative purposes, transaction values can be expressed in US dollars per ounce gold ($/oz) and as $/oz as a percentage of the gold price at the date of the transaction (termed MTR). Previous studies have shown that $/oz and MTR values are significantly higher for producing properties than for non-producing properties, as expected. The present study shows the effect on these value metrics of the gold price, which has increased dramatically in recent years.
