Prismo Metals (CSE PRIZ / WKN A2QEGD) is following up: The company reports final lab results – including re-assays for samples that exceeded the scale – for the first series of 23 samples from the Silver King project in Arizona and also announces a significant expansion of the drilling program.
Particularly striking are silver values of 619 g/t and 511 g/t Ag from the area of the Silver King shaft, as well as 757 g/t silver in a newly described polymetallic vein, accompanied by 1.5% copper (Cu), 6.7% lead (Pb) and 11.5% zinc (Zn). In a separate replacement zone, copper overlimits between 1.11% and 2.43% Cu were also measured. For Prismo Metals, this results in a dynamic picture with several clearly defined target types in a small area.
Prismo Metals: Results in Detail
The data now published specify the preliminary values reported on September 24, 2025 and underpin the metal leadership in several areas of the project. Two samples with 619 g/t and 511 g/t Ag come from the immediate vicinity of the Silver King shaft. A sample with 757 g/t Ag was analyzed in the newly mapped Ag-Pb-Zn vein; at the same time, it contains 1.5% Cu, 6.7% Pb and 11.5% Zn. This combination of elements directs the view beyond silver to base metals, which traditionally play a role in the district.
At the same time, the stratigraphically controlled replacement mineralization provides several samples with copper overlimits: 1.11% to 2.43% Cu. This zone occurs as a larger, contiguous body on the Black Diamond claim. According to the company, the replacement mineralization runs along the same stratigraphic layer that also plays a role at the nearby Magma Mine. Taken together, the results outline three work paths for Prismo Metals: (1) high-grade silver veins in historical mining areas, (2) a polymetallic vein with silver, lead, zinc and copper, and (3) a copper-dominated replacement mineralization.
Silver King in the Context of Resolution Copper and Magma Mine
Silver King is located near Superior, Arizona, in the immediate vicinity of significant deposits: The Resolution Copper deposit (joint venture of Rio Tinto and BHP) is about three kilometers away, as is the high-grade Magma Mine, a former producer of copper and silver. This location is geologically relevant because structural trends and layer contacts can be traced across the deposits.
In addition to the silver-bearing vein systems, mapping on the Prismo Metals claims also shows Cu-Ag veins, a strongly altered intrusive body with stockwork quartz-pyrite mineralization, and the replacement body already mentioned. These observations fit into an environment in which porphyry-related processes and vein/replacement styles can occur side by side – a setting that allows for diverse exploration approaches. For the upcoming drilling campaign, this means that different target types with different geometries and metal signatures are to be systematically tested.
Drilling Program Expanded: Goals, Logistics and Permits
Prior to the recent finds, Prismo Metals had planned approximately 1,000 meters of core drilling to investigate the upper half of a steeply dipping, pipe-shaped silver body, as well as zones adjacent to a dense stockwork system – areas that have historically been the focus. After evaluating the current results, the company is now increasing the approach to a total of approximately 2,000 meters.
The second drilling phase is specifically aimed at newly identified targets outside the immediate historical mining areas: the polymetallic vein and a copper vein. In addition, a follow-up is planned on the voluminous replacement body on the patented Black Diamond claim. This area is accessible by road and is located on private land – a logistical advantage for implementation. According to its own information, Prismo Metals has submitted an operations plan to the U.S. Forest Service; individual locations may require additional permits.
Operationally, the drilling is intended to address three questions: First, how continuous are the high-grade silver zones along the old mine workings? Second, what thicknesses and grades does the Ag-Pb-Zn vein have along the strike, and how does the metal zoning behave? Third, what is the extent of the copper-rich replacement body that stratigraphically connects to regional horizons? Answers to these questions are central to the geological modeling and prioritization of subsequent steps in the Prismo Metals project process.
With the available analyses, Prismo Metals is consolidating the picture of a project area in which peak silver values and copper-rich replacement zones lie close to each other. The combination of reliable lab results, regional context (including Resolution Copper, Magma Mine) and a drilling plan extended to 2,000 meters creates a clear starting position for the next few months. The focus is on precisely locating the geological target types on Silver King – from the silver vein to the copper replacement mineralization – using drilling data and classifying their importance for Prismo Metals’ further work program.
