Our mascot “Grubby” made his first appearance as “Shiftless Sam” in the 1953 ENGINEER yearbook. He was the creation of Jack Ihli (GEOL 55). Many variations of Grubby exist, however the official trademarked version is depicted below.
Grubby is both the primary retail and identifying mark for South Dakota Mines Athletics and a symbol of university affinity for students, alumni, and friends of South Dakota Mines. The use of the primary Grubby logo is limited to Athletics and the Rocker Shop.
The M/Grubby lockup logo is the university’s new spirit mark. This logo can be used by students organizations and departments, but should not be used for official university business. Please contact Marketing & Communications for this logo file.

Under special circumstances, full-body Grubby can be used as a graphical element. However, it should never stand alone as the only logo.
Full-body Grubby must be used in conjunction with the wordmark “South Dakota Mines” in the composition.
Grubby cannot be altered in any way (for example: reversing colors, surrounding him with pickaxes and other accessories, him holding any accessories). Any alterations or enhancements to Grubby must be built and approved by Marketing and Communications.
Our same standard logo guidelines apply to full-body Grubby. Clear space, minimum sizing, and other unapproved usages, as well as contrast guidelines. See here for more information: Logo Guidelines – South Dakota Mines Brand Guidelines
Our standard Color guidelines also apply to any usage of full-body Grubby. Do not mix malachite green with Mines old gold, as well as the 60-30-10 rule when using our color palettes. See here for more information: Colors – South Dakota Mines Brand Guidelines
