WorldWide Drilling Resource®

15 NOVEMBER 2026 WorldWide Drilling Resource® In Memoriam Henry A. “Hank” Baski The WWDR Team was saddened to learn of pioneering inventor and entrepreneur in the groundwater industry, Henry A. “Hank” Baski’s passing on September 14, 2026, in Denver, Colorado, at the age of 87. Born in Cromwell, Minnesota, Hank showed an early interest in building things. As a teenager, his innovative introduction of wooden suspension springs led to his becoming a T.H. Keating Award winner in the 1954 Soap Box Derby. Growing up with the family’s water well drilling business, Hank learned the trade and helped build a cable tool drilling rig for their operations. He went on to earn a bachelor’s degree in geophysics from the University of Minnesota, continued drilling, and helped relocate the family business to Pueblo, Colorado. In 1963, Hank married Alice, a nurse trained at St. Luke’s in Duluth. The couple moved to Pueblo, Colorado, started their family, then relocated to Denver in 1966. There, Hank transitioned to groundwater/hydrology consulting with WrightMcLaughlin Engineers, later joined Dames & Moore, and eventually launched his own groundwater consulting business. Sensing an unmet need for specialized tools in the field, Hank founded Baski Water Instruments in 1978. Together with Alice, they bootstrapped the company, grew it to about 20 employees, and steered it through challenging periods for more than four decades while retaining full ownership. Today, the firm designs and manufactures innovative groundwater equipment, including the market-leading Baski flow control valves, inflatable packers, pitless units, and related products. Hank held 14 patents and was widely recognized in the industry. He served as the 2004 National Ground Water Association (NGWA) William A. McEllhiney Distinguished Lecturer in Water Well Technology and received the NGWA Life Member Award for service in furthering the groundwater industry. Outside the business, Hank and Alice designed and built a unique post and beam home with passive solar heating in Lakewood, Colorado, in 1976. After 57 years of marriage, Alice predeceased Hank in death on Thanksgiving Day, November 26, 2020. Hank is survived by their three children: Alison (Chris), Cort (Kemery), and Keith (Cathy), and by the lasting legacy of his business and all of its technical contributions which continue to serve the hydrology field and groundwater community. The WWDR Team extends their sincerest condolences to Hank’s family, friends, and colleagues. Lest we forget . . . Hook-Carter Uranium Adapted from Information by Greenridge Exploration Inc. Greenridge Exploration Inc. in partnership with Denison Mines Corp., announced their winter drilling program the Hook-Carter Uranium Project with the goal of locating deposits. Located in the Athabasca Basin region of Saskatchewan, Canada, the project is home to several northeastern strike extensions running alongside structural trends including the Derksen Trend and the Patterson Lake Corridor (PLC), with a small host of uranium deposits and traces having been discovered southwest of the project area. Hook-Carter covers an area of about 62,000 acres and is located in the southwest corner of the region approximately 91 miles northeast of La Loche. Hook-Carter is expected to host the northeastern strike extension of the PLC, which hosts NexGen Energy’s Arrow uranium deposit, Paladin Energy Limited’s Triple R uranium deposit, and Purepoint Uranium Group’s Spitfire, Hornet, and Dragon zones in a joint venture with Cameco Corporation and Orano Canada. The Project also overlies strike extensions of the Carter and Derksen corridors, each of which represent highly prospective and underexplored structural corridors. With the recently discovered Patterson Corridor East zone, potential expansion of the width of the PLC might be called for. This year’s drilling program has commenced from a temporary work camp staged on the project site Denison and Greenridge plan to drill up to eight holes totaling approximately 15,092 feet, with drill targets defined through detailed ground geophysical surveys backed up with historical exploration data. Russell Starr, Chief Executive Officer of Greenridge said, “The 2026 drilling Program at Hook-Carter represents the culmination of years of exploration efforts leading to the target areas developed by the joint venture’s work in 2025. The Company is pleased to be working with Denison on one of the most exciting uranium trends in the history of Athabasca Basin exploration.”
