Highland Silver Corp. announced results of grade- shell modelling at its La Estrella project, Central Peru. The Company's 3D grade shell modelling of historic drilling indicates a near surface exploration target (>50 g/t AgEq) of 15 to 35 Mt averaging between 90 and 110 g/t AgEq, containing some 50 to 100 Million Oz AgEq. Ag Equivalent is calculated considering a silver price of USD 20 /Oz Au. Average grades of 50 to 60 g/t Ag and 0.4 to 0.6 g/t Au were considered for the sliver equivalent content of the exploration target. The potential quantity and grade of the exploration target is conceptual in nature and there has been insufficient exploration work and drilling to define a mineral resource and the full potential of the mineralization. Moreover, it is uncertain if further exploration will result in the target being delineated as a mineral resource. The La Estrella acquisition represents an inflection point for the Company and shareholders. The planned work towards an inaugural resource at the project provides the company with significant near-term upside potential. Following the acquisition of the La Estrella project in Central Peru, the Highlander team has been working with the historical drilling data (total of 41 drill holes for 8,500m) to understand the project's exploration potential. A 3D grade shell model has been developed based on the drilling information and observed geological controls. The results indicate a potential near surface, higher grade (>50 g/t AgEQ) exploration target of 15 to 35 Mt averaging between 90 and 110 g/tAgEq, containing some 50 To 100 Million Oz AgEq; The higher grade (>50 g/T AgEq) mineralization is contained within a much larger grade shell of >20 g/t AgEq that is open in multiple directions. It is significant that some of the higher grade drill hole intercepts are open to the South, with a 500m gap to the next drill hole, providing significant additional potential upside. The team will now focus on producing an updated geological model that will underpin the inaugural
resource work to be completed over the coming several months. In addition, the Company will continue to build trust and nurture existing relationships with the local communities and other key stakeholders to create an optimal environment for advancing the project. The Company is also pleased to announce the engagement of Harbor Access Inc. ("Harbor Access"), a strategic cross-border investor relations advisory firm focused on small and mid-cap companies. Under the terms of the agreement, Harbor Access has been engaged for 12 months, commencing on May 15th, 2023 and will be paid a monthly retainer of USD 7,000 and will provide support to build an investor relations strategy, and assist with incoming and outgoing communications. Harbor Access has an office at 107 Elm Street, 4th Floor in Stamford Connecticut and Graham Farrell will be providing the services on their behalf. Graham can be reached at Graham.
