madukubah/sale_mining — reverse-engineered prompt

Build me an Odoo 10 module for handling sale orders for a small mining business. I want it to fit into the normal Sales workflow, but add the mining details we need on each order, like customer, mining product or material, quantity, price, order date, and simple notes about the site or job. Please create the basic Python models, form and list views, menu entries if needed, access rules, and a clean manifest so it can be installed as a normal Odoo add on.

Keep it simple and practical. The goal is that a staff member can open Odoo, create a mining sale order, fill in the relevant details, save it, and see the records later without needing technical knowledge. If there are standard Odoo sale order pieces you can reuse, reuse them instead of building a separate complicated system. This repo has almost no docs, so make reasonable choices for Odoo 10 and keep the module easy to maintain.
