Roski purchased an 80-acre parcel in 1989, and originally planned to build an industrial warehouse on the site, before deciding on a casino instead.

In 2005, there were plans to eventually add other hotels, retail space, and a timeshare facility on the remainder of the Silverton property.

An 18-story timeshare tower – known as The Berkley, Las Vegas – was eventually added in 2016, along with the state's first Cracker Barrel restaurant.

[2] The site is located three miles south of the Las Vegas Strip, at the corner of Interstate 15 and Blue Diamond Road.

[10] Former Nevada governor Robert List was among officers in the new property, serving as senior vice president and corporate counsel.

[11] A month after the opening, Boomtown, Inc. exercised an option to buy out Roski's 50% share of the property's operating company.

[2] Its remote location made it unattractive to locals,[14] and tourists would frequently pass it up in favor of the nearby Las Vegas Strip.

[15] Boomtown's chairman and chief executive officer, Tim Parrot, said that the hotel needed around 1,000 rooms to adequately compete against nearby resorts.

The deal would allow Boomtown to expand the Las Vegas property,[16] although Hollywood Park had little interest in the hotel-casino.

[15] Roski began targeting local residents as the primary demographic, especially people living in nearby Green Valley.

[20] The move towards a younger demographic was inspired by the success of the Rio and Hard Rock resorts in Las Vegas.

The expansion was scheduled to begin in 2001, and a second phase was to add a separate hotel tower and casino on adjacent property.

[28] The upscale Sundance Grill restaurant was added in early 2003, in an effort to attract residents from the affluent Southern Highlands community.

[29] Later that year, the Silverton announced that it would add a Bass Pro Shops Outdoor World as part of a multi-year expansion project.

[30][31][32] The entire resort would replace its mining town theme with an outdoor mountain lodge appearance, matching the Bass Pro store.

[39][40] The aquarium holds 117,000 gallons of water, and includes sting rays and small sharks, in addition to the mermaid performers.

[52] In March 2005, the Silverton announced a master plan to develop the remaining vacant land into a mixed-use resort over the next several years, at a cost of up to $2 billion.

By that point, the Silverton had become popular among new homebuyers in the area, and had also become a tourist-oriented property in part because of its Bass Pro Shop.

The Silverton's clientele included regular visitors from southern California as well as tourists visiting the Las Vegas Strip.

[23] Following the 2008 expansion, concerts were held in temporary venues set up on the property, while plans for a new showroom were considered.

The retail component would include approximately 28,000 sq ft (2,600 m2) spread across four buildings, and was expected to be complete within a year.
