Long before building Contango Silver & Gold, Rick Van Nieuwenhuyse was a young geologist working Alaska’s rugged terrain with Anaconda Minerals in the late 1970s. These two photos capture moments from Rick’s early years in Alaska and a generation of mining professionals who would later help shape the global mining industry. The first photo, taken in 1978, shows Rick field mapping in Alaska’s Ambler District for Anaconda Minerals. The second photo, taken in Southeast Alaska at the Niblack project in 1979, shows Rick alongside: • Former Rio Tinto CEO Tom Albanese • Former United States Geological Survey Mineral Resources Program Director Tom Crafford • Former Newmont Senior VP Dave Baker At the time, they were simply part of the Anaconda field crew: coiling waterline, mapping geology, and working long days in some of Alaska’s most prospective mineral districts. Nearly 50 years later, Rick is still focused on building in Alaska through Contango Silver & Gold. Some things change. The passion for discovery doesn’t. $CTGO

This morning, Rick Van Nieuwenhuyse, CEO, and @ShawnKhunkhun, President, of $CTGO rang the New York Stock Exchange Opening Bell, marking the next chapter following our transformational merger. In their interview on NYSE Live, they share what’s ahead: from scaling production to unlocking long-term value as a growing North American precious metals producer.

“Dr. Copper is breaking out.” @IanHarrisMining joins @DanielaCambone to outline a tightening copper market, with global inventories sitting at ~2 weeks of supply. Mocoa is one of the largest undeveloped copper systems globally (1.1 billion tonnes), a rare, district-scale asset with the size and grade to matter in a structurally undersupplied market.

Frank Giustra and @IanHarrisMining sat down with @JeremySzafron at PDAC 2026 to talk about the coming copper squeeze and why the market may still be underestimating it. Key takeaways from the conversation: • A major infrastructure disruption in the DRC recently exposed just how fragile global copper supply chains can be. The DRC is one of the world’s largest copper producers. • Copper demand is accelerating as electrification, AI data centers, and aging power grids drive a structural increase in energy infrastructure investment. • Very few large, near-surface copper deposits remain undeveloped globally — making Tier-1 assets increasingly strategic for future supply. • Recent industry transactions have highlighted a significant valuation gap between the price paid for copper resources in acquisitions and where many large copper deposits currently trade in public markets. As Frank Giustra puts it: the majors will need to replace reserves and there aren’t many places left to look. Watch the full conversation: youtu.be/0SJe0dLzNKA?si=qIgR… $CGNT.V $LBCMF

“Last year was the year of bullion. This year will be the year of precious metals equities.” I sat down with Shawn Khunkhun to break down why he believes 2026 will be the year mining stocks finally catch up to the metal price rally. @SilverVarden @ShawnKhunkhun

At PDAC 2026 with our largest shareholder, Frank Giustra, at the Copper Giant booth. Copper demand keeps rising. Supply isn’t. AI, electrification, grid upgrades are all copper intensive. Meanwhile, very few large-scale projects are moving forward globally. That’s why Mocoa matters. ✅ 1.1B-tonne resource. ✅ 23,000-metre drill program underway. ✅ District-scale potential. Booth #3128. Come see the core and decide for yourself. $CGNT.V $LBCMF

A full room for the Copper Giant’s stage presentation at VRIC in Vancouver following the updated MRE, alongside a big turnaround at the booth, with Mocoa joining a very small group of near-surface copper systems worldwide that exceed 1B tonnes. Increasingly, investors are positioning early around copper, viewed by many as the next silver in the cycle. $CGNT.V $LBCMF
