Data rooms for mine sales, farm-ins, royalty deals and project finance: handling geological data, technical reports and permits, with which providers fit.
Q&A, granular permissions, dynamic watermarking, document rights control, bulk upload and a full audit trail, with AI tools that help reviewers find their way through large technical archives; from $149 a month.
Sell-side tooling with redaction, analytics, AI tools, SSO and a mobile app, suited to large asset sales run by an investment bank with many international bidders.
Headquartered in Canada, a major mining finance market, with Q&A, redaction, watermarking and SOC 2 plus ISO 27001; a steady choice for mid-sized asset sales and financings.
Headquartered in Australia, another major mining market, with Q&A, SSO, AI tools and SOC 2 plus ISO 27001; a fit for companies that want AI-assisted deal readiness before the room opens.
Redaction, SSO, SOC 2 and ISO 27001 for large transactions, including project financings where lender syndicates apply strict security checks.
A mining or resources deal is decided by technical evidence more than by accounts. Buyers, partners and lenders want to know how much ore or mineral is in the ground, how confident the estimate is, whether the permits will hold, and what it will cost to get the material out. The data room is where that evidence is tested, and much of it is too large and too specialised for a generic file-sharing tool.
| Transaction | Counterparty | What they focus on |
|---|---|---|
| Sale of a mine or exploration project | Miners, private equity, sovereign funds | Resource estimates, permits, closure liabilities |
| Farm-in or joint venture | A partner earning an interest by funding work | Exploration results, work programme, tenure |
| Royalty or streaming deal | Royalty and streaming companies | Mine plan, production forecasts, offtake |
| Project finance | Banks, export credit agencies, development lenders | Feasibility study, capex, environmental compliance |
| Company acquisition or merger | Strategic buyers, often listed | All of the above, plus corporate and tax |
The five layers of a resource asset
Geology and resource estimates usually dominate the upload: drill logs, assay certificates, core photos, block models, maps and the technical report that supports any published resource or reserve. For companies listed in the US, Canada or Australia, that report follows a formal standard (subpart 1300 of the SEC’s Regulation S-K, NI 43-101 and the JORC Code respectively), and bidders will compare the room’s raw data against it.
Tenure and permits prove the seller holds the right to explore or mine. Expect local counsel to check every licence, its expiry and renewal conditions, and any government consent needed for a change of control.
Environment and community documents have moved from a side folder to the centre of diligence. Baseline studies, water and tailings management, closure plans and community agreements all affect value and financing.
Contracts and royalties include offtake agreements, existing royalties or streams, joint venture terms and major service contracts. The financial model ties it together.
Permission groups by discipline. A bidder’s geologists, lawyers, environmental advisers and lenders do not all need every folder. Separate groups keep access tidy and make the audit trail more meaningful: you can see whether the bidder’s technical team actually reviewed the drill data.
Q&A routed to specialists. Technical questions need answers from your geologists or the competent person who signed the report, not the deal team. All five rooms on this page include Q&A in our data; check that questions can be assigned to an expert and approved before release.
Rights control on models and reports. Resource models represent years of exploration spend. Dynamic watermarking and document rights control, offered by all five rooms here in our data, discourage copying when a bidder walks away.
Redaction where needed. Datasite, Firmex and Intralinks offer in-room redaction in our data; Ellty and Ansarada do not, so material such as landholder or employee details would be redacted before upload.
Global access. Resource bidders are spread across North America, Australia, Europe and Asia. A room that works smoothly in a browser, with support available in your bidders’ time zones, matters more here than in a domestic deal. Ask each provider about support hours and where its servers sit.
Most resource deals include a site visit. Use the room to manage it: post the visit schedule, safety induction material and attendee forms, and add any data shown on site to the room afterwards so every bidder has the same information.

Resource deals often stretch: a farm-in negotiation can pause for a drilling season, and project finance diligence runs for months. Monthly pricing handles pauses well, but check storage limits, because technical data is heavy. Ask for a quote based on your real data volume and on the longest realistic timetable. Our pricing page explains the billing models, and the due diligence checklist covers the corporate folders every deal needs.
A report prepared by a qualified or competent person that supports published mineral resources or reserves, following a formal standard such as the SEC's subpart 1300 of Regulation S-K, Canada's NI 43-101 or Australia's JORC Code. Bidders test it against the raw data in the room.
Only where they genuinely need to run the data in their own software, and only for the technical team. Keep watermarking and rights control on, and log every download.
A farm-in partner earns an interest by funding exploration, so the focus is on exploration results, tenure and the proposed work programme rather than a full corporate diligence. The room is often smaller but stays open longer.
