13. Sales of Products

Our products consist of both gold flotation concentrates which in 2020 and 2021 we sold to a broker (H&H Metal), and an unrefined gold-silver product known as doré which we sell to a precious metal refinery. Revenue is recognized upon the completion of the performance obligations and transfer of control of the product to the customer, and the transaction price can be determined or reasonably estimated.

For gold flotation concentrate sales, the performance obligation is met when the transaction price can be reasonably estimated, and revenue is recognized generally at the time when risk is transferred to H&H Metal based on contractual terms. Based on contractual terms, the Company has determined the performance obligation is met and title is transferred to H&H Metal when the Company receives its first provisional payment on the concentrate because, at that time, 1) legal title is transferred to the customer, 2) the customer has accepted the concentrate lot and obtained the ability to realize all of the benefits from the product, 3) the concentrate content specifications are known, have been communicated to H&H Metal, and H&H Metal has the significant risks and rewards of ownership to it, 4) it is very unlikely a concentrate will be rejected by H&H Metal upon physical receipt, and 5) we have the right to payment for the concentrate. Concentrates lots that have been sold are held at our mill up to 60 days, until H&H Metal provides shipping instructions.

Our concentrate sales sometimes involve variable consideration, as they can be subject to changes in metals prices between the time of shipment and their final settlement. However, we can reasonably estimate the transaction price for the concentrate sales at the time of shipment using forward prices for the estimated month of settlement, and previously recorded sales and accounts receivable are adjusted to estimated settlement metals prices until final settlement for financial reporting purposes. The embedded derivative contained in our concentrate sales is adjusted to fair value through earnings each period prior to final settlement. It is unlikely a significant reversal of revenue for any one concentrate lot will occur. As such, we use the expected value method to price the concentrate until the final settlement date occurs, at which time the final transaction price is known. At December 31, 2021, metals that had been sold but not final settled thus exposed to future price changes totaled 2,196 ounces of gold. The Company has received provisional payments on the sale of these ounces with the remaining amount due reflected in gold sales receivable.

Sales and accounts receivable for concentrate shipments are recorded net of charges for treatment and other charges negotiated by us with H&H Metal, which represent components of the transaction price. Charges are estimated by us upon transfer of risk of the concentrates based on contractual terms, and actual charges typically do not vary materially from our estimates. Costs charged by the customer include fixed treatment, refining and costs per ton of concentrate and may include penalty charges for lead and zinc content above a negotiated baseline as well as excessive moisture.

For sales of doré and of metals from doré, the performance obligation is met, the transaction price is known, and revenue is recognized at the time of transfer of control of the agreed-upon metal quantities to the customer.

Sales of products by metal for the years ended December 31, 2021, and 2020 were as follows:

Sales by significant product type for the years ended December 31, 2021 and 2020 were as follows:

In 2021 and 2020 floatation concentrates sold to H&H Metals Corp accounted 95% of all gold sales. The remaining 5% in 2021 and 2020 was doré sold to a third party. At December 31, 2021 and 2020, our gold sales receivable balance related to contracts with customers of $408,187 and $264,779, respectively, consist only of amounts due from H&H Metal. There is no allowance for doubtful accounts. We have determined our contracts do not include a significant financing component. For doré sales, payment is received at the time the performance obligation is satisfied. Consideration for concentrate sales is variable, and we receive payment for a significant portion of the estimated value of concentrate parcels at the time the performance obligation is satisfied.
