SugarGold Export

We are documented Seller Mandates of 6 mining companies in Africa, we have a lot of Gold to sell you.
I can send the Gold CIF via Guarantee, which can be:
* SBLC = CIF FULL (average cost of 3% for the buyer) Price: $65,000/kg with PB from Bank Zenith, or LBMA Price - 8% with PB from JP Morgan
* CIF Collateral = CIF FULL (cost 0$ for the buyer) $57,000/kg
This CIF COLLATERAL procedure has been widely used because it does not generate any cost for the Buyer in the acquisition of GOLD.
Export costs related to taxes, insurance, smelting, documentation, freight and customs clearance fees are paid by the buyer and the initial payment is deducted from the final payment when the goods arrive at the buyer's destination. A gold security equivalent to the initial amount paid for export costs is held in joint custody with the security company until the goods reach the buyer's final destination, at which point the security is returned to the seller. This is widely used by buyers who do not want to incur SBLC costs but will attend or send their representative to the TTM meeting, pay for the export documentation and place the gold with the seller in joint custody at a Security House.

These are different prices and procedures, I need you to tell me which one is for your client.
