Hopeless About Retirement? Hopeless and Helpless Aren’t the Same Thing (Ad)

Your retirement date didn't move once - it moved slowly, then repeatedly, until the shift felt normal. That's not personal failure. That's what happens when the environment your retirement depends on changes without you ever being told. The cost shows up later, as the retirement you didn't get to live. Garrett Goggin, CFA, CMT, Lead Analyst at Golden Portfolio, breaks down exactly how much this drift is costing you - and what you can do about it.tc pixel

A 3M Oz. Historical Gold Resource And A Market That Hasn't Caught Up (Ad)

One Canadian junior explorer controls a gold and copper system in British Columbia's Kootenay Golden Arc - a district with over 4 million ounces of historical production. Surrounded by major operators including Coeur Mining and Centerra, the project holds a historical resource estimated at 3.31 million ounces of gold. With funding and permits in place for an active drill program and an updated NI 43-101 resource targeted for 2027, the setup offers multiple near-term catalysts - all against a backdrop of gold near record highs and a structurally short copper market.tc pixel
