Overview
Laguna Resources was the later corporate identity of an Australian company originally incorporated as Southern Pacific Petroleum NL in February 1968. The company entered the public market on the Australian Securities Exchange in May of the same year and initially operated as an oil company. From 1973, its principal activities centered on oil-shale exploration and the development of shale-oil extraction projects. During the 1980s, Southern Pacific Petroleum and Central Pacific Minerals NL collaborated with Esso Australia on the Rundle oil-shale deposit in Queensland. Although the project represented a substantial attempt to commercialize Australian oil shale, active development was deferred by Esso in the late 1980s. The companies later pursued the Stuart Oil Shale Project. In 1997, they entered into a joint venture with Canadian energy company Suncor Energy, which acted as project operator. Suncor withdrew from the project in April 2001, leaving Southern Pacific Petroleum and Central Pacific Minerals as the sole shareholders. The two Australian companies merged in February 2002, with Southern Pacific Petroleum becoming the holding company for the combined interests. The business subsequently experienced severe financial difficulties. Trading in Southern Pacific Petroleum shares was suspended on 25 October 2003. After a fixed and floating charge had been granted to Sandco Koala LLC, receivers were appointed in December 2003. The receivers sold the Stuart Oil Shale Project and other assets to the newly established Queensland Energy Resources in February 2004. The remaining important interest in the Rundle joint venture was later sold to Australian Oil-Shale Holdings in May 2007. A recapitalization proposal backed by Ascent Capital was accepted in September 2007, and shareholders approved the transaction in May 2008. As part of the restructuring, interests held by third parties in the Glassford Tenement in Central Queensland were transferred to the company. The company returned its focus to mineral-resource exploration and development, and its shares were reinstated to quotation in 2008. To reflect the shift away from oil shale and toward minerals, Southern Pacific Petroleum changed its name to Laguna Resources in 2009. Under the Laguna Resources name, the company pursued gold, silver, and copper exploration. Its principal Australian asset was the approximately 136-hectare Glassford Tenement, located about 70 kilometres south of Gladstone and 15 kilometres southwest of Nargoorin in Central Queensland. The tenement contained copper-, silver-, and gold-bearing skarn lodes, and Laguna Resources proposed exploration work to test geochemical anomalies for potentially economic mineralization. The company also explored and developed gold and silver projects in the Maricunga Gold Belt of northern Chile. Laguna Resources ultimately became part of Kingsgate Consolidated Limited following a successful takeover. Its shares were delisted in February 2012, ending its life as an independently traded Australian resource company. The corporate history illustrates a transition from oil-shale development to mineral exploration, followed by financial restructuring and acquisition.
History
Laguna Resources originated as Southern Pacific Petroleum NL, an Australian oil company incorporated on 6 February 1968. It was listed on the Australian Securities Exchange on 16 May 1968. Beginning in 1973, the company concentrated on oil-shale exploration and shale-oil extraction rather than conventional petroleum activities. In the mid-1980s, Southern Pacific Petroleum and Central Pacific Minerals NL formed a joint venture with Esso Australia to develop the Rundle oil-shale deposit in Queensland. Esso later deferred the project, and active development ended in the late 1980s. The companies then pursued the Stuart Oil Shale Project. A 1997 joint venture brought in Suncor Energy of Canada, which was appointed project operator. Suncor left the project in April 2001, after which Southern Pacific Petroleum and Central Pacific Minerals held the project interests themselves. The two companies merged in February 2002, with Southern Pacific Petroleum serving as the holding company. The company encountered financial distress in the early 2000s. Trading in its shares was suspended on 25 October 2003. A charge granted to Sandco Koala LLC led to the appointment of receivers on 2 December 2003. On 13 February 2004, the receivers sold the Stuart Oil Shale Project and other assets to Queensland Energy Resources. The company's remaining important asset was its interest in the Rundle joint venture, which was sold to Australian Oil-Shale Holdings on 11 May 2007. The business was subsequently restructured. Ascent Capital's recapitalization proposal was accepted in September 2007, and shareholders approved the plan on 28 May 2008. The restructuring also transferred third-party interests in the Glassford Tenement in Central Queensland to the company. Its shares were reinstated to quotation in 2008, and the company redirected its strategy toward mineral-resource exploration and development. In 2009, Southern Pacific Petroleum changed its name to Laguna Resources. The new company pursued mineral projects rather than oil shale, including gold and silver opportunities in the Maricunga Gold Belt of northern Chile. In Australia, its Glassford Tenement covered approximately 136 hectares about 70 kilometres south of Gladstone and 15 kilometres southwest of Nargoorin. The tenement contained copper-, silver-, and gold-bearing skarn lodes. Laguna Resources planned exploration programs to test major geochemical anomalies for potentially economic mineralization. Laguna Resources was later acquired by Kingsgate Consolidated Limited. Following the successful takeover, its shares were delisted in February 2012. The company therefore ended as an independently listed entity after a corporate evolution from oil-shale development to mineral exploration.
