To implement e-signatures: 1) Select a compliant e-signature platform that adheres to Australian standards. 2) Prepare the contract digitally, ensuring all parties' identities are verified. 3) Upload the document to the platform and assign signers with roles (e.g., signatory, witness). 4) Send for signing, allowing remote execution suitable for mining sites. 5) Store signed documents securely with audit trails for evidentiary purposes. In the resources sector, prioritize platforms supporting multi-party workflows for joint venture agreements.
