Metallon Corporation Limited v Stanmarker Mining (Private) Limited

Lonmin Plc (UK) decided in 2001 to dispose of shares in Cableair Ltd, which owned Independence Gold Mining Zimbabwe (Pvt) Ltd, which in turn owned five gold mines in Zimbabwe. Metallon Corporation (a South African company) and Stanmarker Mining (a Zimbabwean company) initially expressed independent interest in acquiring the shares but then decided to submit a joint bid. On 24 June 2002, they concluded a "Heads of Agreement" setting out main principles for negotiating detailed written agreements. Clause 2.2 stated that only clauses 2.3, 9, 10 and 11 were legally binding, with other provisions not constituting legally binding obligations. Clause 2.3 imposed a three-month restraint period during which parties would negotiate in good faith and not negotiate with others. Clause 3.5 (not listed as legally binding) stated Metallon would negotiate with Lonmin on behalf of the proposed new company ("Newco"). Before and during negotiations, Metallon acted through associate companies (First Gold and later Pemberton International Investments). By 24 September 2002, negotiations had not succeeded. On 28 October 2002, Pemberton concluded an agreement with Lonmin to purchase the shares for US$15.5 million. Stanmarker sued Metallon for breach of contract, claiming Metallon used Pemberton to acquire shares for itself in breach of the Heads of Agreement.

• Whether the Heads of Agreement constituted a partnership between Metallon and Stanmarker
• Whether clause 3.5 of the Heads of Agreement was legally binding on Metallon despite not being expressly listed in clause 2.2 as a binding provision
• Whether Metallon breached any legal obligation under clause 3.5 to negotiate on behalf of Newco
• Whether Metallon had a legal obligation to continue negotiating with Lonmin on behalf of Newco after the three-month restraint period expired on 24 September 2002
• The proper interpretation of contractual terms distinguishing between binding and non-binding provisions in heads of agreement

1. The appeal is allowed with costs of two counsel. 2. The order of the court a quo is set aside and the following is substituted: "The plaintiff's claim is dismissed with costs of two counsel". 3. The cross-appeal is dismissed with costs.

1. The essential elements of a partnership (derived from Pothier on Partnership) require: (a) each partner bringing something into the partnership; (b) the business being carried on for the joint benefit of both parties; and (c) the object being to make profit. The requirement that business be carried on for joint benefit is crucial and its absence is fatal to establishing a partnership. 2. In interpreting heads of agreement or preliminary contracts, where parties expressly designate certain clauses as legally binding and others as non-binding, courts must give effect to that manifest intention. 3. Mere reference to a non-binding clause within a binding clause does not convert the referenced clause into a binding obligation. 4. The word "shall" in contractual provisions is not invariably peremptory; its meaning depends on context and the manifest intention of the parties as gleaned from the agreement as a whole. Where giving "shall" peremptory effect would contradict the parties' express intentions or create absurdity, it should not be so interpreted. 5. Restraint periods in commercial agreements are to be strictly construed according to their express terms. Once a defined restraint period expires, parties are free to act independently unless there are other continuing legal obligations.

The Court noted that Stanmarker's allegation of partnership appeared to be an afterthought, only raised in the replication filed in February 2006, long after the declaration (April 2004), further particulars (June 2004), and amendment to declaration (June 2005). If Stanmarker genuinely believed a partnership existed, it should have alleged this in its original pleadings or when responding to requests for particulars about the duty of good faith. The Court observed that the main allegation in paragraph 10 of the declaration (that Metallon breached the agreement during the three-month restraint period) was unsustainable. The Court also indicated it need not comment on the applicability of the High Court's reasoning regarding continuing obligations in actual partnership transactions, having found no partnership existed in this case.

This case is significant in Zimbabwean commercial law for establishing important principles regarding the interpretation of heads of agreement and preliminary commercial arrangements. It clarifies: (1) the distinction between binding and non-binding provisions in heads of agreement, emphasizing that parties' express intentions must be respected; (2) that mere reference to a clause in a binding provision does not automatically make that referenced clause binding; (3) the essentials of partnership under common law, particularly that there must be a business carried on for the joint benefit of parties; (4) that the word "shall" is not always peremptory and must be interpreted in context; and (5) that restraint periods in commercial agreements will be strictly construed according to their terms. The case serves as a warning that informal preliminary agreements or "heads of agreement" will not necessarily create enforceable partnerships or continuing obligations beyond expressly stated restraint periods. It reinforces freedom of contract and the principle that courts will give effect to the parties' manifest intentions as expressed in clear contractual language.
