- Flagship Francisca property, located about 80 km NW of Salta City, Argentina, has been optioned on favorable terms: Up to 85% over 7 years by making cash payments totalling USD $2.2 million and USD $2.0 million of expenditures.
- Salta is a region of good infrastructure where numerous large-scale copper, gold, and lithium projects are being developed. The property has moderate terrain, limited vegetation and good road access for exploration year-round.
- Politically, Javier Milei, the President of Argentina, is moving the Country to a morepro-business and free enterprise footing.
- Orestone is targeting an oxide gold deposit mineable by open pit.
- Gold/silver mineralization outcrops on the crest of a moderate-relief hill for 1100metres along strike. Two gold zones have been identified to date; each zone has a surface expression of 400- 450 m in strike length and 50- 100 m in width. Previous exploration between 1996- 1999 and in 2006 included mapping, sampling, trenching, IP geophysics, and limited shallow core drilling.

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.
