Colombia, 1905

In 1905, the total Colombian platina yield (82% ore) was estimated at 923.86 kgs (757.56 kgs. Pt .999); the US export (~112 kgs.) was just ~12% the total.

1905: 1 Troy Ounce platina (Colombian ore, Spot, Est. 80%) ~$ 4.75 - 5.
1905: 1 Troy Oz. Pt (Colombian Spot, @ .999) ~ USD$ 5.94 - 6.27

Colombia, 1910

In 1910, total export of Colombian platina was estimated to be 311.04 kgs (255.05 kgs. Fine Pt) ;  kgs or % of the total was exported to the USA.

At the US valuation of USD$ 20.67, Colombia produced  5,070.6 kgs. of Fine Gold; platina ore (82% Pt) was % the Gold yield and % the total Au/Pt estimate; at purity, Platinum (~ kgs) was % of the Colombian Au/Pt yield.

Colombia, 1911

In 1911, total export of Colombian platina was estimated to be 373.25 kgs (306.06 Fine Pt) where 198.16 kgs or 53.09% of the total ore was exported to the USA.  (Fiscal Year, June-June, lowers Pt Totals.)  Where the value was estimated at  £69,179, with an estimated purity of 80-85%.  The chief town for platina trade was Istamina (San Pablo) and Novita.

1911: 1 Troy Ounce platina (Colombian, 82%) = £ 5.7648

June 1910 - June 1911: 171.18 kgs

January 1910 - January 1911: 198.16 kgs

At the US valuation of USD$ 20.67, Colombia produced 5,153.36 kgs. of Fine Gold; platina ore (82% Pt) was 7.24% the Gold yield and 6.75% the total Au/Pt estimate; at purity, Platinum (~306 kgs) was 5.24% of the Colombian Au/Pt yield.

Colombia, 1913

In 1913, export of Quibdo platina from Cartagena was estimated at 249.55 kgs, nearly as much as the Gold-ore but curiously, with the suspicion the total Chocó export was 'twice as high.' Later totals (1918) would imply the platina export from Buenaventura was ~217 kgs:  466.56 kgs (USD$ 507,000) in 1913.  Of the entire Colombian yield, 325.38 kgs or 69.74% of the total was exported to the USA. 

The 2.88% difference between Cartagena and New York prices (USD$ 0.97) might account for shipping and insurance costs.

Factoring the telegraph, New York news arrived about ~30 days later.  

Cartagena merchants "paid" miners 30% the last month's New York Spot for intrinsic Platinum, additionally deducting for 'impurities' (other PGMs) on which they actually realized additional profit in sales to New York buyers.  Assuming 84% purity ore and whereas local Silver Pesos in Chocó were officially rated C$1.38 per Troy Oz.,  per English Troy Ounce of platina, local miners received:

USD$/C$ 34.77 * 33% = $11.58 * 90% = C$ 10.42

Poorer still for the intrinsic coin-silver value, the equivalent 7.538 Troy Ounces Silver (C$) was theoretically worth just USD$ 0.604 per Oz = USD$ 4.55!

Colombia, 1854

According to an American visitor, by 1854 the Gold Yield had collapsed -75% from years prior to 1852.

The issue of contraband export dogged estimates well in the 1850s.  Assuming the Franc/Piastre exchange at 5:1 and the Colombian Fine-Gold Price at S$ 17.61 per English Ounce Troy, a rather unlikely massive export of 7,949 kg of Gold occurred circa 1854.  

Likewise, the amount of Colombian platina exported (S$ 30,000 or 188.71 kgs) was barely 2.35% the Gold total but probably much closer to the true export amount.

As reported in 1857 (somewhat dated?) Colombia was annually exporting 600 kilograms or ~ 19,290 ozt platina.
