Sugarloaf Mills, formerly Discover Mills, is a single-story shopping mall in suburban Atlanta, located in Lawrenceville in Gwinnett County, Georgia, near the interchange of Interstate 85 and Highway 316. Opened in 2001, the mall features 14 anchors, 184 specialty retailers, and a variety of theme restaurants, casual dining, and entertainment venues.
The Mills Corporation began planning Sugarloaf Mills as a joint venture with KanAm on a 230-acre site at Interstate 85 and Sugarloaf Parkway in Gwinnett County, and an initial budget of $170 million. The original (and now current) name, Sugarloaf Mills was named after the mall's planned situation near Sugarloaf Parkway. The site began getting ready for construction in early 2000. 80% of the property was cleared by March.
The mall opened on November 2, 2001, as Discover Mills. The name change from Sugarloaf Mills to Discover Mills was because of a 10-year co-marketing partnership with Discover Financial Services, which acquired the naming rights in exchange for promoting the card as the preferred payment option and integrating special offers with the mall's stores and restaurants. It was one of the first malls in the United States to do so. The Mills Corporation had granted the naming rights specifically to Discover Card, and thus originally given the name Discover Mills as well as the tagline "Where Discover Card Is The Smart Choice".
Discover Mills became a "shoppertainment" mall following additions of AMC Theatres (operating as AMC Discover Mills 18) in December 2003, and Medieval Times in 2006.
In February 2007, The Mills Corp.'s portfolio, including Discover Mills, would be acquired by Simon Property Group and Farallon Capital Management for $1.64 billion, following the rejection of Brookfield Asset Management's offer, which offered to acquire The Mills Corp. for $1.35 billion. This was because The Mills Corporation was financially struggling by May 2006. The acquisition was completed in April 2007, and Discover Mills' branding was relaunched as The Mills: A Simon Company.
In November 2009, Dave & Busters opened at Discover Mills, replacing Jillian's Entertainment.
In March 2012, Simon Property Group acquired full control of Discover Mills by buying out Farallon's stake in the Mills portfolio for $1.5 billion.
In October 2012, the naming rights with Discover Card expired. Instead of renewing the naming rights, Simon Property Group reverted the mall to its original planning name, Sugarloaf Mills. Following the renaming, Simon renovated Sugarloaf Mills to reflect the new name. This included the rebranding of AMC Discover Mills 18 to AMC Sugarloaf Mills 18.
Simon Property Group struggled to refinance over $100 million in debt of Sugarloaf Mills in September 2018, leading to concerns regarding imminent default. CWCapital Asset Management took over a $105M and $18.4M loan held by Omega Advisors on September 13. Simon corrected the issue by reducing the principal balance by over 25% on the senior note from $135 million to about $100 million, preventing the risk of foreclosure.
In October 2025, Primark announced that it would open a 30,000-square-foot store in 2026, replacing the former Neiman Marcus Last Call.
