Key Flags & Risks
▼
Sublease Expires April 29, 2030
BDE holds this site via sublease, not ownership. The sublease runs through April 29, 2030 with a renewal option. Track the renewal window; failure to exercise renewal or renegotiate could disrupt operations.
Assignment Requires DIGTB Consent for Further Transfer
Any further assignment or transfer of the Schedule 1 contracts (including this sublease) requires written consent from DIGTB, Inc. (Assignor). This limits BDE's flexibility to sublease or assign without approval.
$175,000 ESA Refund Obligation to DIGTB
Per the ESA amendment: if BDE ever receives a refund of the $175,000 (or any portion), BDE is contractually required to forward that amount to DIGTB, Inc. Monitor for any future refund events and ensure compliance.
Power Position — North West Rural Electric Coop
The site power infrastructure is tied to the North West Rural Electric Cooperative as master lessor. Maintain strong relationship with the Cooperative to protect both the sublease renewal and power access for continued crypto mining operations.
Strategic Neighbor — POET Biorefining (259.95 ac, ~$25M Assessed)
POET Biorefining-Arthur LLC holds an adjacent ~260-acre industrial parcel assessed at nearly $25M. This is a corporate subsidiary of POET (major biorefinery), not an individual owner. Any approach should be framed as a neighbor-to-neighbor strategic conversation. Entry point: Jack Mitchell, Plant GM (712) 973-0900. Escalation: Doug Berven, VP Corporate Affairs, POET HQ (605) 965-2200.
Recommended Next Actions
▼
1
Calendar the sublease renewal window — April 29, 2030 expiry
Identify the renewal notice period in the sublease (typically 90–180 days prior). Set a reminder to engage North West Rural Electric Cooperative at least 12 months before expiry to negotiate renewal or extension terms.
2
Confirm sublease renewal option terms with North West Rural Electric Cooperative
Contact the Cooperative to confirm renewal mechanics, any rent escalation, and notice requirements. The sublease was originally entered by DIGTB; ensure BDE is recognized as the current party. Ida County contacts can help identify the Coop's address and rep if needed.
3
Verify DIGTB, Inc. (Assignor) status and contact info
Any further assignment of the Hosting Agreement or Sublease requires DIGTB consent. Confirm current DIGTB contact (address: Delaware Corporation — check state registry) in case consent is ever needed. Also confirm the $175K ESA refund has not been triggered.
4
Relationship call with POET Arthur plant — Jack Mitchell (712) 973-0900
As a neighbor-to-neighbor strategic conversation, assess if POET has any appetite to sell or lease a portion of their adjacent ~260-acre parcel. Don't lead with acquisition; build the relationship first. Confirm Mitchell is still GM. Escalation path: Doug Berven, VP Corporate Affairs, POET HQ — (605) 965-2200 / d.berven@poet.com.
5
Confirm zoning with Ida County — (712) 364-2628
Verify Enterprise Zone / Industrial designation on both the BDE subleased parcel and the adjacent POET parcel. This affects any future expansion or permitting.
6
Review Compass Mining Service Order No. 1 and current operational status
Ensure the hosting relationship with Compass Mining is current, uptime SLAs are being met, and any customer hardware return/swap obligations are tracked. Monitor for any termination triggers that could affect site economics.
