Let’s Discuss Your Appraisal/Valuation Project Needs

You can phone directly at +1 303-399-4361 to discuss your project or expert witness needs (ask for Trevor Ellis). Otherwise, please complete the form below to schedule a phone conversation.

During our conversation, we will:

    • Ask you questions to understand your mineral property, the interest to be appraised, and the purpose of the valuation;
    • Find out the exploration, development, or operating status of your property, and the kinds of documents available;
    • Share our experience working on similar appraisal projects;
    • Discuss your timing needs, our availability, and give you a rough cost estimate for what it will take to develop your appraisal;
    • Then, if we are not the right fit, we will likely be able to refer you to another resource.


As our expert you were able to provide tremendous assistance in educating us, and the court, concerning the different qualities of the rock, its age, the location of granite seams, [and] the amount of granite gneiss on the site. Your thorough, hands on inspection of the site, your tremendous knowledge of geology and the mining industry, and your thorough preparation, in my opinion, created the foundation of our recovery.
