The Waterpump Creek (Pb-Zn-Ag) target is a carbonate replacement style deposit (“CRD”) hosted by the Illinois Creek dolomite sequence. The dolomite sequence is similar to that which hosts the main Illinois Creek oxide gold deposit. The CRD target is a distal segment of the greater Illinois Creek hydrothermal system that includes historic Illinois Creek oxide gold deposit.
Between 1982 and 2005 Anaconda Minerals Company and NovaGold Resources drilled 58 diamond drill holes identifying high-grade silver-lead-zinc mineralization. Exploration drilling by WAM is further defining and expanding the CRD mineralization originally discovered by Anaconda.

Geology & Exploration
Nine drill holes were completed by WAM at Waterpump Creek target in 2021. The drilling focused primarily on delineating shallow oxide silver mineralization previous drilled by Anaconda and NovaGold. The Company also completed two drill holes to test the historically recognized sulfide CRD mineralization at depth. Drill hole WPC21-09 cut 10.5-meter (9.1 meters true thickness) of 522 g/t Ag, 22.5% Zn and 14.4% Pb of massive intergrown sphalerite and argentiferous galena down-dip of the historical drilling. This exceptional high-grade interval turned the focus on exploration, targeting the overall CRD potential on the property.
WAM’s 2002 drill program rapidly expanded and delineated the Waterpump Creek Ag-Pb-Zn CRD mineralization with multiple, thick, high-grade silver-lead-zinc intercepts. Waterpump Creek remains open to the continued expansion of the mineralization footprint. The 2023 infill and step-out drilling to date has returned expected results of additional high-grade silver intervals. Click here for the latest news.
The mineralization at Waterpump Creek has very similar geological characteristics to many of the most well known and prolific CRD systems exploited in North America including the Santa Eulalia and Naica deposits in Mexico, the Taylor-Sunnyside deposit in Arizona and the Tintic deposit in Utah). These CRD replacement deposits show continuous mineralization over multi-kilometer distances.
