Butte & Superior Copper Co. v. Clark-Montana Realty Co.
Headline: Affirms older mining claim protects underground ore rights when vein apex lies beneath it, blocking rival company’s claim to the Rainbow Lode and preserving owners’ access.
Holding: The Court affirmed the lower courts, ruling that the earlier Elm Orlu claim owners have rights to underground ore that extend beyond the surface lines (extralateral rights) when the vein’s apex lies within their claim.
- Confirms original surface claimant keeps underground ore rights when apex lies within their claim.
- Blocks rival company from claiming ore taken under the Elm Orlu’s protected veins.
- Leaves some vein boundaries open for further development and accounting.
Summary
Background
The dispute is between the owners of the Elm Orlu claim (Clark-Montana Realty Company and its lessee Elm Orlu Mining Company) and a neighboring mining company (Butte & Superior Copper Company, Limited). The Elm Orlu owners say they discovered and worked the Rainbow vein first, held continuous possession, received a patent, and that the rival company has secretly tunneled in and taken ore. The rival company owns adjoining claims (including Black Rock) and asserts competing rights under its own locations and patents.
Reasoning
The Court examined whether the Elm Orlu owners’ earlier discovery and open possession gave them rights to underground ore that extend beyond surface lines when a vein’s highest point (apex) lies inside their claim. The Court denied a motion to dismiss, accepted the trial court’s factual findings that Elm Orlu had prior location and possession, and agreed that those facts support rights to the veins whose apices are in Elm Orlu. The Court rejected the rival’s argument that state-recording defects defeated Elm Orlu’s claim, and it treated surface patents as determining surface rights but not necessarily controlling underground apex rights.
Real world impact
The decision leaves the Elm Orlu owners entitled to the ore under veins that apex inside their claim, and it upholds the lower courts’ accounting and injunction orders. Some specific questions—such as exactly how far a particular strand’s apex extends under the neighbor’s ground—were left open for further development, so parts of the dispute may continue in later proceedings.
