Máximo Cristóbal Valdespino, a self-proclaimed famous explorer, can be found southwest of Horseshoe Overlook. He has apparently travelled to the country to hunt for treasure but wishes to leave the United States the next day. He offers to sell the player a treasure map of the location where Jack Hall Gang's gold is stashed.
After meeting with Máximo, players should decline his first offer of $10 for the map in order for him to lower the price to $5. If the player scared him away, robbed or killed him by accident, they can buy his map from any fence in the game.
The player should stay in the Horseshoe Overlook area and travel slightly northwards from where they meet Maxímo; there is a mountain called Caliban's Seat. If approached from north to south, there will be a pathway which will lead the protagonist up the mountain. Upon reaching the top, players should look for a small camp at the end, then head down to the right from the camp, and snack their way down the cliff side. After clearing a gap by jumping across the rock wall, the player will notice a crack in the rock face where the first treasure is located.
The second treasure can be found in the state of Ambarino, in a small location known as Cotorra Springs. The player should travel to the area and look for the the largest rock at its top, as this is where the treasure can be found. If the player is having trouble finding the prompt to pull the treasure, they should consider doing a slow loop around the rock until it appears.
The third and final treasure can be found east of Cotorra Springs in an area known as O'Creagh's Run, in Grizzlies East. This area is a large lake with a small island - that's where players should want to look. Th protagonist should swim to the island's south side and look for a loose rock on the flat rock face. Once they search the spot, they'll be rewarded two Gold Bars for their trouble. Each Gold Bar fetches $500; the player can choose to sell them to a Fence or donate it to the camp's funds.
- The episode's title is taken from the line "All that glitters is not gold", used most commonly in William Shakespeare's The Merchant of Venice.
