Excelsior Springs, Mo. — A proposed mining expansion in rural Clay County could be facing new obstacles after the Excelsior Springs City Council voted during a special session at 9:00 a.m. on Thursday, June 5, to pursue annexation of a large area of unincorporated land. The proposal includes property owned by David Rhodus, the landowner who had previously sought to annex into Mosby in support of Ideker Mining’s northward expansion.
The ordinance, which passed unanimously, places the annexation question on the November 4, 2025, ballot, allowing Excelsior Springs voters to decide whether nearly 50 parcels, including roads, farmland, and residential properties, should be brought into the city limits.
Excelsior Springs city officials stated that the proposal aligns with long-term development plans, as new residential and commercial growth continues west of the existing city boundary.
Although Excelsior’s city leaders did not directly frame the annexation as an effort to halt mining, the action could significantly complicate Ideker’s expansion. If successful, the land would fall under Excelsior Springs zoning and regulatory oversight, giving the city authority to govern future mining activity in the area.
Economic Development Director Melinda Mehaffy has said that quarry activity in the area has discouraged industrial and manufacturing prospects. She explained that many modern manufacturing operations rely on robotics, which are highly sensitive to seismic vibrations caused by blasting.
A little-known detail adds further dimension to the issue: just last month, on May 16, 2025, Ideker Mining purchased approximately 168 acres just south of its current operating site. That property already lies within the boundaries of Excelsior Springs, meaning any future development on that land would be subject to the city’s zoning regulations. The new annexation proposal would effectively extend that regulatory reach northward, placing additional constraints on Ideker’s expansion plans.
At 6:00 pm on June 5, 2025, the Mosby City Council met to consider Rhodus’ request for annexation into Mosby. However, council members voted to table the matter, citing the need for more information. The rural residents presented them with documentation of Excelsior Springs’ ordinance, prompting surprise among Mosby officials and an acknowledgment that the issue would require legal review.

The Mosby meeting drew strong emotions from residents of both Mosby and unincorporated Clay County. Citizens expressed concern about the effects of the mine, including noise, dust, sinkholes, and declining property values. Many urged Mosby leaders to reject the annexation request from Rhodus and voiced support for Excelsior Springs’ intervention.
“I was pretty upset when I learned about Excelsior’s plan last night, but after I thought about it, I think it’d be okay… I’m just thankful someone is finally stepping up to help stop Ideker,” said Chris McClaskey after the Excelsior Springs Council’s special session.
As the situation continues to unfold, the City of Mosby has now scheduled a special meeting for June 17 at 6:00 p.m. for the mayor and aldermen to discuss and vote on the annexation request. According to a public notice announcing the meeting sent on June 9, 2025, there will be “no public voice” permitted at the meeting.
If Mosby has not yet held a formal public hearing as required, a vote without one may not satisfy legal requirements for voluntary annexation under state law.
With Excelsior Springs having already taken formal action, and its ordinance scheduled for a public vote in November, the question of jurisdiction may soon be settled — either by the voters or by further legal review.
