Mineral 1886 is a bar and coffee cafe on the ground floor of the Historic Delaware Hotel in downtown Leadville, Colorado. The coffee cafe opens with the sun from 7 am to noon every day, serving Dazbog coffee pulled to order, teas, chillers, energy revivers, and boba. Breakfast features burritos rolled at six, English muffins baked fresh every morning, Forrest's muffins, and house donuts.

In the evenings from 5:30 to 10 pm, the bar lights up under the chandeliers of the 1886 silver boom hotel, offering fourteen-inch pizzas including the House Pie and Colorado Green Chile, smash burgers, wings, salads, and plates to share, along with cocktails, beer, and wine. The kitchen serves until 9 pm. Hotel guests and locals are welcome at both venues, with morning entry through the lobby and evening access at the bar.
