Actual holdings will vary for each client or fund and there is no guarantee that a particular account will hold any or all of the securities discussed. All investing involves risk including risk of loss. Crescat target resource estimates (TSE) are based on internal modeling and geologic estimates, and include various assumptions based on analysis of geology, geophysics, geochemistry, historic drill assays, and metallurgical recovery data received to date. TSE are discounted based on drilling progress to date, an assessment of the management and technical team's strengths and weaknesses affecting their ability to advance the project, and environmental, local community, and government permitting risk factors. Estimates are displayed on a gold equivalent basis based on current price-to-gold ratios for silver, copper, and other metals if the primary metal is other than gold. Further drilling, assaying, resource modeling, and engineering studies will be required to determine whether Crescat's TSE can be reasonably expected to be achieved. Crescat's target resource estimates are updated monthly across the entire portfolio. Sources: Crescat Capital LLC, Bloomberg, Issuer. Expected profitability percentile is based on Crescat's geologic estimates of projected grades, recoveries, capex, and operational costs on the primary project compared to the universe of operating mines. This value does not project overall anticipated company profitability.
