Event(s), participation(s), dividend(s) 

Report of the Compagnie du Kivu of 1940-45, this case did not seem to meet the expectations of its leaders who tried to provoke its start (21-(1948 T6) -2743 to 45). The Société Minière de la Tele carried out research and exploitation work on behalf of the Company.

1947 - Report of the Compagnie du Kivu of 1948. It was mentioned that the Company made a profit of 639,579.79 francs which was written off on the first establishments (21-(1953 T3) -2268).

1948 - Report of the Compagnie du Kivu of 1949. An unfavorable balance of 1,548,375.20 francs was written back. In the second half of the year, efforts were focused on prospecting and the construction of camps and access roads (21-(1950 T3) -2268). 

1949 - Report of the Compagnie du Kivu of 1950. For the 1949 financial year, the balance sheet mentioned that the previous losses were reduced to 812,074.17 francs. The increased production and the recovery of the tin price could lead to more satisfactory results (21-(1951 T3) -2603). 

1950 - Report of the Compagnie du Kivu of 1951. Prospects remain good. The balance sheet as at December 31, 1950 leaves a profit of 987,988.15 francs after the previous loss has been cleared and allocated to depreciation. This profit made it possible to distribute an initial dividend of 30 francs net per share (21-1952 T3) -2513).

Comparative production from the 1940s to 1950s: 
(21-(1951 T3) -2422 (Société Minière de la Tele)
1951 - Mining production during the year amounted to 105,150 tons of cassiterite containing an average of 69.87% tin. Sales for the year were 83 tons of tin and this was achieved through the intervention of the Société Générale des Minerais. The number of tables in operation increased from 7 in 1950 to 12 in 1951, which made it possible to compensate for the decrease in cassiterite content by increasing the cubic content.
As far as the mining estate is concerned, the number of deposits granted as at December 31, 1951 was 8 with a surface area of 15,185 hectares. Three applications for tin deposits were still pending, i.e. 4,460 hectares. After an allocation of 2,629,225.72 to depreciation, the financial year showed a profit of 1,552,915.87 francs (21-(1953 T4) -3460/61).

1952 - Production during the financial year was 56,670 tons of cassiterite containing an average of 71.21% tin and 3 tons of mixed tantalifère. The 1952 balance sheet showed no profit or loss (21-(1953 T4) -3460/61).

1953 - An agreement was reached with the Société Minière de la Tele to continue to undertake the technical work of the Company in Africa. The production was 62,100 tons of cassiterite containing an average of 71.67% and 5 tons of mixed tantalifère. As at December 31, 1953, 13 mining permits covering an area of 25,000 hectares were granted to the Company, of which 8 for cassiterite and 5 for mixed minerals (cassiterite and columbo tantalite). For the three mining applications covering 1,488 hectares remained pending. The 1953 financial year closed with a loss of 993,658 francs (21-(1954 T4) -3632).

1954 - Production in 1954 amounted to 87,780 tons of cassiterite containing an average of 74.5% tin. At the end of 1954, 16 mining permits covering an area of 26,497 hectares were granted to the Company, 10 for tin (covering 13,198 hectares) and 6 for tin and columbo-tantalite (covering 13,269 hectares). The Company also held 7 special exploration permits, 3 for gold and 4 for tin and mixed columbo-tantalite. The balance sheet as at 31 December 1954, after allocation of 1,308,333 francs for depreciation, left a loss increased from 993,658 to 1,794,637 francs (21-(1956 T4) -3926).

1955 - Production amounted to 58.315 tons compared to 87.780 tons the previous year. This decline in production was the result of depletion of the deposits and was accentuated during the first months of 1955 and fell to 10.872 tons for the first four months of 1956. At this stage, the operations were unprofitable, and the Council, following the advice of the Société Minière de la Tele, decided to stop production definitively on 30 June 1956.
Unfavorable appraisal of the Company's mining properties and no elements gave reason to hope for the continuation of profitable operations.
The profit and loss account at December 31, 1955, after allocation of 4,426,413 francs to depreciation, the total loss was increased from 1,794,637 francs to 4,948,050 francs (21-(1956 T4) -3926).

Dissolution and liquidation

The state of the Company's affairs, the lack of prospects for developing its concessions and the size of the loss incurred led the Company's EGM to put it into early liquidation on October 1, 1956 (21-(1956 T4) -3926). 

Three liquidation distributions were made: 175 francs on April 1, 1957, 70 francs on August 1, 1957 and 47 francs on March 3, 1959 (21-(1957 T1/1958 T4) -1023/4008).
