Grinnell College selects ProStar's SaaS Solution to manage Its 150-year-old infrastructure

ProStar Holdings Inc. ("ProStar ® " or the "the Company") (OTCQX: MAPPF) (TSXV: MAPS) (FSE: 5D00), a world leader in Precision Mapping Solutions, is pleased to announce that Grinnell College has selected ProStar's solution, PointMan®, to improve the management and maintenance of its critical infrastructure on its over 150-year-old, 120-acre campus.

"Grinnell College is located on 120 acres with miles of buried telecom infrastructure critical to operations. To protect and maintain our expanding and valued buried infrastructure, we realized the need for precise maps and accurate locates. We selected ProStar's PointMan platform from our search for a GIS mapping platform that was easy to adopt, met our precision requirements for reference and locating needs, and flexibility for future GIS needs," said David Ellis, Director of Network Services, Grinnell College.

Founded in 1846, Grinnell College is one of the top-ranked residential liberal arts and sciences colleges. Located in Grinnell Iowa, Grinnell College is home to about 1,700 students committed to contributing to the common good that embraces intellectual journeys of all kinds and follows their passions across the world.

"The adoption of PointMan by Grinnell College is once again validation of the value that ProStar provides to entities that span Fortune 500 firms, government agencies, engineering surveying firms, municipalities, and colleges," stated Page Tucker, CEO, and Founder of ProStar. "Not knowing the precise location of underground infrastructure is becoming a growing concern. After all, it is not only a major risk to the safety of the public, the environment but also students and facility members on campuses which are small cities."
